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.
