starting metadata sunset (#69454)

* starting metadata sunset

 - purged metadata from any requirements
 - fix indent in generic handler for yaml content (whey metadata display was off)
 - make more resilient against bad formed docs
 - removed all metadata from docs template
 - remove metadata from schemas
 - removed mdata tests and from unrelated tests

-  Keen Python programmers may notice that contrary to PEP 8's advice we don't put ``imports`` at the top of the file. This is because the ``ANSIBLE_METADATA`` through ``RETURN`` sections are not used by the module code itself; they are essentially extra docstrings for the file. The imports are placed after these special variables for the same reason as PEP 8 puts the imports after the introductory comments and docstrings. This keeps the active parts of the code together and the pieces which are purely informational apart. The decision to exclude E402 is based on readability (which is what PEP 8 is about). Documentation strings in a module are much more similar to module level docstrings, than code, and are never utilized by the module itself. Placing the imports below this documentation and closer to the code, consolidates and groups all related code in a congruent manner to improve readability, debugging and understanding.

 ANSIBLE_METADATA block
 ======================
 
-After the shebang, the UTF-8 coding, the copyright, and the license, your module file should contain an ``ANSIBLE_METADATA`` section. This section provides information about the module for use by other tools. For new modules, the following block can be simply added into your module:
+Since we moved to collections we have deprecated the METADATA functionality, it is no longer required for modules, but it will not break anything if present.
 
-.. code-block:: python

-   ANSIBLE_METADATA = {'metadata_version': '1.1',

-.. warning::
-
-   * ``metadata_version`` is the version of the ``ANSIBLE_METADATA`` schema, *not* the version of the module.
-   * Promoting a module's ``status`` or ``supported_by`` status should only be done by members of the Ansible Core Team.
-
-Ansible metadata fields
------------------------
-
-:metadata_version: An "X.Y" formatted string. X and Y are integers which
-   define the metadata format version. Modules shipped with Ansible are
-   tied to an Ansible release, so we will only ship with a single version
-   of the metadata. We'll increment Y if we add fields or legal values
-   to an existing field. We'll increment X if we remove fields or values
-   or change the type or meaning of a field.
-   Current metadata_version is "1.1"
-
-:supported_by: Who supports the module.
-   Default value is ``community``. For information on what the support level values entail, please see
-   :ref:`Modules Support <modules_support>`. Values are:
-
-   * core
-   * network
-   * certified
-   * community
-   * curated (*deprecated value - modules in this category should be core or
-     certified instead*)
-
-:status: List of strings describing how stable the module is likely to be. See also :ref:`module_lifecycle`.
-   The default value is a single element list ["preview"]. The following strings are valid
-   statuses and have the following meanings:
-
-   :stableinterface: The module's options (the parameters or arguments it accepts) are stable. Every effort will be made not to remove options or change
-      their meaning. **Not** a rating of the module's code quality.
-   :preview: The module is in tech preview. It may be
-      unstable, the options may change, or it may require libraries or
-      web services that are themselves subject to incompatible changes.
-   :deprecated: The module is deprecated and will be removed in a future release.
-   :removed: The module is not present in the release. A stub is
-      kept so that documentation can be built. The documentation helps
-      users port from the removed module to new modules.

 ===================
 
-After the shebang, the UTF-8 coding, the copyright line, the license, and the ``ANSIBLE_METADATA`` section comes the ``DOCUMENTATION`` block.

You may find it easier to start writing your ``DOCUMENTATION`` string in an :ref:`editor with YAML syntax highlighting <other_tools_and_programs>` before you include it in your Python file. You can start by copying our `example documentation string <https://github.com/ansible/ansible/blob/devel/examples/DOCUMENTATION.yml>`_ into your module file and modifying it. If you run into syntax issues in your YAML, you can validate it on the `YAML Lint <http://www.yamllint.com/>`_ website.
