Use ArgumentSpecValidator in AnsibleModule (#73703)
* Begin using ArgumentSpecValidator in AnsibleModule

* Add check parameters to ArgumentSpecValidator

Add additional parameters for specifying required and mutually exclusive parameters.
Add code to the .validate() method that runs these additional checks.

* Make errors related to unsupported parameters match existing behavior

Update the punctuation in the message slightly to make it more readable.
Add a property to ArgumentSpecValidator to hold valid parameter names.

* Set default values after performining checks

* FIx sanity test failure

* Use correct parameters when checking sub options

* Use a dict when iterating over check functions

Referencing by key names makes things a bit more readable IMO.

* Fix bug in comparison for sub options evaluation

* Add options_context to check functions

This allows the parent parameter to be added the the error message if a validation
error occurs in a sub option.

* Fix bug in apply_defaults behavior of sub spec validation

* Accept options_conext in get_unsupported_parameters()

If options_context is supplied, a tuple of parent key names of unsupported parameter will be
created. This allows the full "path" to the unsupported parameter to be reported.

* Build path to the unsupported parameter for error messages.

* Remove unused import

* Update recursive finder test

* Skip if running in check mode

This was done in the _check_arguments() method. That was moved to a function that has no
way of calling fail_json(), so it must be done outside of validation.

This is a silght change in behavior, but I believe the correct one.

Previously, only unsupported parameters would cause a failure. All other checks would not be executed
if the modlue did not support check mode. This would hide validation failures in check mode.

* The great purge

Remove all methods related to argument spec validation from AnsibleModule

* Keep _name and kind in the caller and out of the validator

This seems a bit awkward since this means the caller could end up with {name} and {kind} in
the error message if they don't run the messages through the .format() method
with name and kind parameters.

* Double moustaches work

I wasn't sure if they get stripped or not. Looks like they do. Neat trick.

* Add changelog

* Update unsupported parameter test

The error message changed to include name and kind.

* Remove unused import

* Add better documentation for ArgumentSpecValidator class

* Fix example

* Few more docs fixes

* Mark required and mutually exclusive attributes as private

* Mark validate functions as private

* Reorganize functions in validation.py

* Remove unused imports in basic.py related to argument spec validation

* Create errors is module_utils

We have errors in lib/ansible/errors/ but those cannot be used by modules.

* Update recursive finder test

* Move errors to file rather than __init__.py

* Change ArgumentSpecValidator.validate() interface

Raise AnsibleValidationErrorMultiple on validation error which contains all AnsibleValidationError
exceptions for validation failures.

Return the validated parameters if validation is successful rather than True/False.

Update docs and tests.

* Get attribute in loop so that the attribute name can also be used as a parameter

* Shorten line

* Update calling code in AnsibleModule for new validator interface

* Update calling code in validate_argument_spec based in new validation interface

* Base custom exception class off of Exception

* Call the __init__ method of the base Exception class to populate args

* Ensure no_log values are always updated

* Make custom exceptions more hierarchical

This redefines AnsibleError from lib/ansible/errors with a different signature since that cannot
be used by modules. This may be a bad idea. Maybe lib/ansible/errors should be moved to
module_utils, or AnsibleError defined in this commit should use the same signature as the original.

* Just go back to basing off Exception

* Return ValidationResult object on successful validation

Create a ValidationResult class.
Return a ValidationResult from ArgumentSpecValidator.validate() when validation is successful.
Update class and method docs.
Update unit tests based on interface change.

* Make it easier to get error objects from AnsibleValidationResultMultiple

This makes the interface cleaner when getting individual error objects contained in a single
AnsibleValidationResultMultiple instance.

* Define custom exception for each type of validation failure

These errors indicate where a validation error occured. Currently they are empty but could
contain specific data for each exception type in the future.

* Update tests based on (yet another) interface change

* Mark several more functions as private

These are all doing rather "internal" things. The ArgumentSpecValidator class is the preferred
public interface.

* Move warnings and deprecations to result object

Rather than calling deprecate() and warn() directly, store them on the result object so the
caller can decide what to do with them.

* Use subclass for module arg spec validation

The subclass uses global warning and deprecations feature

* Fix up docs

* Remove legal_inputs munging from _handle_aliases()

This is done in AnsibleModule by the _set_internal_properties() method. It only makes sense
to do that for an AnsibleModule instance (it should update the parameters before performing
validation) and shouldn't be done by the validator.

Create a private function just for getting legal inputs since that is done in a couple of places.

It may make sense store that on the ValidationResult object.

* Increase test coverage

* Remove unnecessary conditional

ci_complete

* Mark warnings and deprecations as private in the ValidationResult

They can be made public once we come up with a way to make them more generally useful,
probably by creating cusom objects to store the data in more structure way.

* Mark valid_parameter_names as private and populate it during initialization

* Use a global for storing the list of additonal checks to perform

This list is used by the main validate method as well as the sub spec validation.

*******
Ansible
*******

Ansible is a radically simple IT automation system. It handles
configuration management, application deployment, cloud provisioning,
ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex
changes like zero-downtime rolling updates with load balancers easy. More information on `the Ansible website <https://ansible.com/>`_.

Design Principles
=================

*  Have a dead-simple setup process with a minimal learning curve.
*  Manage machines very quickly and in parallel.
*  Avoid custom-agents and additional open ports, be agentless by
   leveraging the existing SSH daemon.
*  Describe infrastructure in a language that is both machine and human
   friendly.
*  Focus on security and easy auditability/review/rewriting of content.
*  Manage new remote machines instantly, without bootstrapping any
   software.
*  Allow module development in any dynamic language, not just Python.
*  Be usable as non-root.
*  Be the easiest IT automation system to use, ever.

Use Ansible
===========

You can install a released version of Ansible with ``pip`` or a package manager. See our
`installation guide <https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html>`_ for details on installing Ansible
on a variety of platforms.

Red Hat offers supported builds of `Ansible Engine <https://www.ansible.com/ansible-engine>`_.

Power users and developers can run the ``devel`` branch, which has the latest
features and fixes, directly. Although it is reasonably stable, you are more likely to encounter
breaking changes when running the ``devel`` branch. We recommend getting involved
in the Ansible community if you want to run the ``devel`` branch.

Get Involved
============

*  Read `Community
   Information <https://docs.ansible.com/ansible/latest/community>`_ for all
   kinds of ways to contribute to and interact with the project,
   including mailing list information and how to submit bug reports and
   code to Ansible.
*  Join a `Working Group
   <https://github.com/ansible/community/wiki>`_, an organized community devoted to a specific technology domain or platform.
*  Submit a proposed code update through a pull request to the ``devel`` branch.
*  Talk to us before making larger changes
   to avoid duplicate efforts. This not only helps everyone
   know what is going on, but it also helps save time and effort if we decide
   some changes are needed.
*  For a list of email lists, IRC channels and Working Groups, see the
   `Communication page <https://docs.ansible.com/ansible/latest/community/communication.html>`_

Coding Guidelines
=================

We document our Coding Guidelines in the `Developer Guide <https://docs.ansible.com/ansible/devel/dev_guide/>`_. We particularly suggest you review:

* `Contributing your module to Ansible <https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_checklist.html>`_
* `Conventions, tips, and pitfalls <https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_best_practices.html>`_

Branch Info
===========

*  The ``devel`` branch corresponds to the release actively under development.
*  The ``stable-2.X`` branches correspond to stable releases.
*  Create a branch based on ``devel`` and set up a `dev environment <https://docs.ansible.com/ansible/latest/dev_guide/developing_modules_general.html#common-environment-setup>`_ if you want to open a PR.
*  See the `Ansible release and maintenance <https://docs.ansible.com/ansible/devel/reference_appendices/release_and_maintenance.html>`_ page for information about active branches.

Roadmap
=======

Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8).
The `Ansible Roadmap page <https://docs.ansible.com/ansible/devel/roadmap/>`_ details what is planned and how to influence the roadmap.

Authors
=======

Ansible was created by `Michael DeHaan <https://github.com/mpdehaan>`_
and has contributions from over 5000 users (and growing). Thanks everyone!

`Ansible <https://www.ansible.com>`_ is sponsored by `Red Hat, Inc.
