Module validation: sanity check mutually_exclusive, required_if, required_xxx ... (#66961)
* required_if checks should have three or four parts.

* Validate mutually_exclusive, required_together, required_one_of, required_if and required_by.

* Simplify code.

* Improve messages.

* Add changelog.

* Sanity check.

* Update docs.

* Update ignore.txt.

* Don't continue with tests when terms are not strings.

* Remove ignore.txt entry.

* Make sure validate-modules doesn't choke on things already flagged by schema test.

* Check required_if requirements list for strings.

cd /path/to/ansible/source
source hacking/env-setup
ansible-test sanity --test validate-modules
Help
====
.. code:: shell

modules Path to module or module directory
optional arguments:
-h, --help show this help message and exit
-w, --warnings Show warnings
--exclude EXCLUDE RegEx exclusion pattern
--arg-spec Analyze module argument spec
--base-branch BASE_BRANCH
Used in determining if new options were added
--format {json,plain}
Output format. Default: "plain"
--output OUTPUT Output location, use "-" for stdout. Default "-"
Extending validate-modules
==========================
The ``validate-modules`` tool has a `schema.py <https://github.com/ansible/ansible/blob/devel/test/lib/ansible_test/_data/sanity/validate-modules/validate_modules/schema.py>`_ that is used to validate the YAML blocks, such as ``DOCUMENTATION`` and ``RETURNS``.
