Subject: [PATCH 007/185] chore: migrate to owl bot (#16)

This PR migrates from autosynth to [owl bot](https://github.com/googleapis/repo-automation-bots/tree/master/packages/owl-bot).  owl bot will save time for maintainers as it will automatically open PRs when there are updates in [googleapis-gen](https://github.com/googleapis/googleapis-gen/tree/master/google) without requiring maintainers to run `synthtool` to build the client from protos. Additionally, similar to autosynth, PRs will be automatically opened when there are template updates.

+*************************
+Samples and code snippets
+*************************
+
+Code samples and snippets live in the `samples/` catalogue. Feel free to
+provide more examples, but make sure to write tests for those examples.
+Each folder containing example code requires its own `noxfile.py` script
+which automates testing. If you decide to create a new folder, you can
+base it on the `samples/snippets` folder (providing `noxfile.py` and
+the requirements files).
+
+The tests will run against a real Google Cloud Project, so you should
+configure them just like the System Tests.
+
+- To run sample tests, you can execute::
+
+   # Run all tests in a folder
+   $ cd samples/snippets
+   $ nox -s py-3.8
+
+   # Run a single sample test
+   $ cd samples/snippets
+   $ nox -s py-3.8 -- -k <name of test>

-# Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of
-experience, education, socio-economic status, nationality, personal appearance,
-race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-*   Using welcoming and inclusive language
-*   Being respectful of differing viewpoints and experiences
-*   Gracefully accepting constructive criticism
-*   Focusing on what is best for the community
-*   Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-*   The use of sexualized language or imagery and unwelcome sexual attention or
-    advances
-*   Trolling, insulting/derogatory comments, and personal or political attacks
-*   Public or private harassment
-*   Publishing others' private information, such as a physical or electronic
-    address, without explicit permission
-*   Other conduct which could reasonably be considered inappropriate in a
-    professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, or to ban temporarily or permanently any
-contributor for other behaviors that they deem inappropriate, threatening,
-offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-This Code of Conduct also applies outside the project spaces when the Project
-Steward has a reasonable belief that an individual's behavior may have a
-negative impact on the project or its community.
-
-## Conflict Resolution
-
-We do not believe that all conflict is bad; healthy debate and disagreement
-often yield positive results. However, it is never okay to be disrespectful or
-to engage in behavior that violates the project’s code of conduct.
-
-If you see someone violating the code of conduct, you are encouraged to address
-the behavior directly with those involved. Many issues can be resolved quickly
-and easily, and this gives people more control over the outcome of their
-dispute. If you are unable to resolve the matter for any reason, or if the
-behavior is threatening or harassing, report it. We are dedicated to providing
-an environment where participants feel welcome and safe.
-
-
-Reports should be directed to *googleapis-stewards@google.com*, the
-Project Steward(s) for *Google Cloud Client Libraries*. It is the Project Steward’s duty to
-receive and address reported violations of the code of conduct. They will then
-work with a committee consisting of representatives from the Open Source
-Programs Office and the Google Open Source Strategy team. If for any reason you
-are uncomfortable reaching out to the Project Steward, please email
-opensource@google.com.
-
-We will investigate every complaint, but you may not receive a direct response.
-We will use our discretion in determining when and how to follow up on reported
-incidents, which may range from not taking action to permanent expulsion from
-the project and project-sponsored spaces. We will notify the accused of the
-report and provide them an opportunity to discuss it before any action is taken.
-The identity of the reporter will be omitted from the details of the report
-supplied to the accused. In potentially harmful situations, such as ongoing
-harassment or threats to anyone's safety, we may take action without notice.
-
-## Attribution
-
-This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
-available at
-https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-############
-
-#. **Please sign one of the contributor license agreements below.**
-#. Fork the repo, develop and test your code changes, add docs.
-#. Make sure that your commit messages clearly describe the changes.

-
-.. contents:: Here are some guidelines for hacking on the Google Cloud Client libraries.
-
-***************
-Adding Features
-***************
-
-In order to add a feature:
-
-- The feature must be documented in both the API and narrative
-  documentation.
-
-- The feature must work fully on the following CPython versions:
-  3.7, 3.8, 3.9, 3.10 and 3.11 on both UNIX and Windows.
-
-- The feature must not add unnecessary dependencies (where
-  "unnecessary" is of course subjective, but new dependencies should
-  be discussed).
-
-****************************
-Using a Development Checkout
-****************************
-
-You'll have to create a development environment using a Git checkout:
-
-- While logged into your GitHub account, navigate to the
-  ``python-appengine-admin`` `repo`_ on GitHub.
-
-- Fork and clone the ``python-appengine-admin`` repository to your GitHub account by
-  clicking the "Fork" button.
-
-- Clone your fork of ``python-appengine-admin`` from your GitHub account to your local
-  computer, substituting your account username and specifying the destination
-  as ``hack-on-python-appengine-admin``.  E.g.::
-
-   $ cd ${HOME}
-   $ git clone git@github.com:USERNAME/python-appengine-admin.git hack-on-python-appengine-admin
-   $ cd hack-on-python-appengine-admin
-   # Configure remotes such that you can pull changes from the googleapis/python-appengine-admin
-   # repository into your local repository.
-   $ git remote add upstream git@github.com:googleapis/python-appengine-admin.git
-   # fetch and merge changes from upstream into main
-   $ git fetch upstream
-   $ git merge upstream/main
-
-Now your local repo is set up such that you will push changes to your GitHub
-repo, from which you can submit a pull request.
-
-To work on the codebase and run the tests, we recommend using ``nox``,
-but you can also use a ``virtualenv`` of your own creation.
-
-.. _repo: https://github.com/googleapis/python-appengine-admin
-
-Using ``nox``
-=============
-
-We use `nox <https://nox.readthedocs.io/en/latest/>`__ to instrument our tests.
-
-- To test your changes, run unit tests with ``nox``::
-    $ nox -s unit
-
-- To run a single unit test::
-
-    $ nox -s unit-3.11 -- -k <name of test>
-
-
-  .. note::
-
-    The unit tests and system tests are described in the
-    ``noxfile.py`` files in each directory.
-
-.. nox: https://pypi.org/project/nox/
-
-*****************************************
-I'm getting weird errors... Can you help?
-*****************************************
-
-If the error mentions ``Python.h`` not being found,
-install ``python-dev`` and try again.
-On Debian/Ubuntu::
-
-  $ sudo apt-get install python-dev
-
-************
-Coding Style
-************
-- We use the automatic code formatter ``black``. You can run it using
-  the nox session ``blacken``. This will eliminate many lint errors. Run via::
-
-   $ nox -s blacken
-
-- PEP8 compliance is required, with exceptions defined in the linter configuration.
-  If you have ``nox`` installed, you can test that you have not introduced
-  any non-compliant code via::
-
-   $ nox -s lint
-
-- In order to make ``nox -s lint`` run faster, you can set some environment
-  variables::
-
-   export GOOGLE_CLOUD_TESTING_REMOTE="upstream"
-   export GOOGLE_CLOUD_TESTING_BRANCH="main"
-
-  By doing this, you are specifying the location of the most up-to-date
-  version of ``python-appengine-admin``. The
-  remote name ``upstream`` should point to the official ``googleapis``
-  checkout and the branch should be the default branch on that remote (``main``).
-
-- This repository contains configuration for the
-  `pre-commit <https://pre-commit.com/>`__ tool, which automates checking
-  our linters during a commit.  If you have it installed on your ``$PATH``,
-  you can enable enforcing those checks via:
-
-.. code-block:: bash
-
-   $ pre-commit install
-   pre-commit installed at .git/hooks/pre-commit
-
-Exceptions to PEP8:
-
-- Many unit tests use a helper method, ``_call_fut`` ("FUT" is short for
-  "Function-Under-Test"), which is PEP8-incompliant, but more readable.
-  Some also use a local variable, ``MUT`` (short for "Module-Under-Test").
-
-********************
-Running System Tests
-********************
-
-- To run system tests, you can execute::
-
-   # Run all system tests
-   $ nox -s system
-
-   # Run a single system test
-   $ nox -s system-3.8 -- -k <name of test>
-
-
-  .. note::
-
-      System tests are only configured to run under Python 3.8.
-      For expediency, we do not run them in older versions of Python 3.
-
-  This alone will not run the tests. You'll need to change some local
-  auth settings and change some configuration in your project to
-  run all the tests.
-
-- System tests will be run against an actual project. You should use local credentials from gcloud when possible. See `Best practices for application authentication <https://cloud.google.com/docs/authentication/best-practices-applications#local_development_and_testing_with_the>`__. Some tests require a service account. For those tests see `Authenticating as a service account <https://cloud.google.com/docs/authentication/production>`__.
-
-*************
-Test Coverage
-*************
-
-- The codebase *must* have 100% test statement coverage after each commit.
-  You can test coverage via ``nox -s cover``.
-
-******************************************************
-Documentation Coverage and Building HTML Documentation
-******************************************************
-
-If you fix a bug, and the bug requires an API or behavior modification, all
-documentation in this package which references that API or behavior must be
-changed to reflect the bug fix, ideally in the same commit that fixes the bug
-or adds the feature.
-
-Build the docs via:
-
-   $ nox -s docs
-
-*************************
-Samples and code snippets
-*************************
-
-Code samples and snippets live in the `samples/` catalogue. Feel free to
-provide more examples, but make sure to write tests for those examples.
-Each folder containing example code requires its own `noxfile.py` script
-which automates testing. If you decide to create a new folder, you can
-base it on the `samples/snippets` folder (providing `noxfile.py` and
-the requirements files).
-
-The tests will run against a real Google Cloud Project, so you should
-configure them just like the System Tests.
-
-- To run sample tests, you can execute::
-
-   # Run all tests in a folder
-   $ cd samples/snippets
-   $ nox -s py-3.8
-
-   # Run a single sample test
-   $ cd samples/snippets
-   $ nox -s py-3.8 -- -k <name of test>
-
-********************************************
-Note About ``README`` as it pertains to PyPI
-********************************************
-
-The `description on PyPI`_ for the project comes directly from the
-``README``. Due to the reStructuredText (``rst``) parser used by
-PyPI, relative links which will work on GitHub (e.g. ``CONTRIBUTING.rst``
-instead of
-``https://github.com/googleapis/python-appengine-admin/blob/main/CONTRIBUTING.rst``)
-may cause problems creating links or rendering the description.

-Supported Python Versions
-*************************
-
-We support:
-
--  `Python 3.7`_
--  `Python 3.8`_
--  `Python 3.9`_
--  `Python 3.10`_
--  `Python 3.11`_

-
-Supported versions can be found in our ``noxfile.py`` `config`_.
-
-.. _config: https://github.com/googleapis/python-appengine-admin/blob/main/noxfile.py
-
-
-We also explicitly decided to support Python 3 beginning with version 3.7.
-Reasons for this include:
-
--  Encouraging use of newest versions of Python 3
--  Taking the lead of `prominent`_ open-source `projects`_
--  `Unicode literal support`_ which allows for a cleaner codebase that
-   works in both Python 2 and Python 3
-
-.. _prominent: https://docs.djangoproject.com/en/1.9/faq/install/#what-python-version-can-i-use-with-django

-.. _Unicode literal support: https://www.python.org/dev/peps/pep-0414/
-
-**********
-Versioning
-**********
-
-This library follows `Semantic Versioning`_.
-
-.. _Semantic Versioning: http://semver.org/
-
-Some packages are currently in major version zero (``0.y.z``), which means that
-anything may change at any time and the public API should not be considered
-stable.

-
-Quick Start
------------
-
-In order to use this library, you first need to go through the following steps:
-
-1. `Select or create a Cloud Platform project.`_
-2. `Enable billing for your project.`_
-3. `Enable the App Engine Admin.`_
-4. `Setup Authentication.`_
-
-.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
-.. _Enable billing for your project.: https://cloud.google.com/billing/docs/how-to/modify-project#enable_billing_for_a_project
-.. _Enable the App Engine Admin.:  https://cloud.google.com/appengine/docs/admin-api/
-.. _Setup Authentication.: https://googleapis.dev/python/google-api-core/latest/auth.html
-
-Installation
-~~~~~~~~~~~~
-
-Install this library in a `virtualenv`_ using pip. `virtualenv`_ is a tool to
-create isolated Python environments. The basic problem it addresses is one of
-dependencies and versions, and indirectly permissions.
-
-With `virtualenv`_, it's possible to install this library without needing system
-install permissions, and without clashing with the installed system
-dependencies.
-
-.. _`virtualenv`: https://virtualenv.pypa.io/en/latest/
-
-
-Mac/Linux
-^^^^^^^^^
-
-.. code-block:: console
-
-    pip install virtualenv
-    virtualenv <your-env>
-    source <your-env>/bin/activate
-    <your-env>/bin/pip install google-cloud-appengine-admin
-
-
-Windows
-^^^^^^^
-
-.. code-block:: console
-
-    pip install virtualenv
-    virtualenv <your-env>
-    <your-env>\Scripts\activate
-    <your-env>\Scripts\pip.exe install google-cloud-appengine-admin
-

-   Because this client uses :mod:`grpc` library, it is safe to
-   share instances across threads. In multiprocessing scenarios, the best
-   practice is to create client instances *after* the invocation of
-   :func:`os.fork` by :class:`multiprocessing.pool.Pool` or
-   :class:`multiprocessing.Process`.

-                are specified, the client will attempt to ascertain the
-                credentials from the environment.
-            transport (Union[str, DomainMappingsTransport]): The
-                transport to use. If set to None, a transport is chosen
-                automatically.
-            client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]): Custom options for the
-                client. It won't take effect if a ``transport`` instance is provided.
-                (1) The ``api_endpoint`` property can be used to override the
-                default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT
-                environment variable can also be used to override the endpoint:
-                "always" (always use the default mTLS endpoint), "never" (always
-                use the default regular endpoint) and "auto" (auto switch to the
-                default mTLS endpoint if client certificate is present, this is
-                the default value). However, the ``api_endpoint`` property takes
-                precedence if provided.
-                (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
-                is "true", then the ``client_cert_source`` property can be used
-                to provide client certificate for mutual TLS transport. If
-                not provided, the default SSL client certificate will be used if
-                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
-                set, no client certificate will be used.
-            client_info (google.api_core.gapic_v1.client_info.ClientInfo):
-                The client info used to send a user-agent string along with
-                API requests. If ``None``, then default info will be used.

-
-    Interceptors are used to manipulate requests, request metadata, and responses
-    in arbitrary ways.
-    Example use cases include:
-    * Logging
-    * Verifying requests according to service or custom semantics
-    * Stripping extraneous information from responses
-
-    These use cases and more can be enabled by injecting an
-    instance of a custom subclass when constructing the InstancesRestTransport.

-                (1) The ``api_endpoint`` property can be used to override the
-                default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT
-                environment variable can also be used to override the endpoint:
-                "always" (always use the default mTLS endpoint), "never" (always

-                the default value). However, the ``api_endpoint`` property takes
-                precedence if provided.
-                (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
-                is "true", then the ``client_cert_source`` property can be used

-class VersionsRestInterceptor:

-
-    Interceptors are used to manipulate requests, request metadata, and responses
-    in arbitrary ways.
-    Example use cases include:
-    * Logging
-    * Verifying requests according to service or custom semantics
-    * Stripping extraneous information from responses
-
-    These use cases and more can be enabled by injecting an
-    instance of a custom subclass when constructing the VersionsRestTransport.

-
-    Attributes:
-        name (str):
-            Full path to the Version resource in the API. Example:
-            ``apps/myapp/services/default/versions/v1``.
-
-            @OutputOnly
-        id (str):

-        automatic_scaling (google.cloud.appengine_admin_v1.types.AutomaticScaling):
-            Automatic scaling is based on request rate,
-            response latencies, and other application
-            metrics. Instances are dynamically created and
-            destroyed as needed in order to handle traffic.

-            This field is a member of `oneof`_ ``scaling``.
-        basic_scaling (google.cloud.appengine_admin_v1.types.BasicScaling):
-            A service with basic scaling will create an
-            instance when the application receives a
-            request. The instance will be turned down when
-            the app becomes idle. Basic scaling is ideal for

-            A service with manual scaling runs
-            continuously, allowing you to perform complex
-            initialization and rely on the state of its
-            memory over time. Manually scaled versions are
-            sometimes referred to as "backends".
-
-            This field is a member of `oneof`_ ``scaling``.
-        inbound_services (MutableSequence[google.cloud.appengine_admin_v1.types.InboundServiceType]):

-Install PortAudio
-+++++++++++++++++
-
-Install `PortAudio`_. This is required by the `PyAudio`_ library to stream
-audio from your computer's microphone. PyAudio depends on PortAudio for cross-platform compatibility, and is installed differently depending on the
-platform.
-
-* For Mac OS X, you can use `Homebrew`_::
-
-      brew install portaudio
-
-  **Note**: if you encounter an error when running `pip install` that indicates
-  it can't find `portaudio.h`, try running `pip install` with the following
-  flags::
-
-      pip install --global-option='build_ext' \
-          --global-option='-I/usr/local/include' \
-          --global-option='-L/usr/local/lib' \
-          pyaudio
-
-* For Debian / Ubuntu Linux::
-
-      apt-get install portaudio19-dev python-all-dev
-
-* Windows may work without having to install PortAudio explicitly (it will get
-  installed with PyAudio).
-
-For more details, see the `PyAudio installation`_ page.
