* Add tests for check_mode at play and task level
These test inheritance of check_mode from the various levels (command
line, as a play attribute and as a task attribute) so they will be
useful for checking that the change to fieldattribute inheritance with
defaults works
* Add a sentinel object
The Sentinel object can be used in place of None when we need to mark an
entry as being special (usually used to mark something as not having
been set)
* Start of using a Sentinel object instead of None.
* Handle edge cases around use of Sentinel
* _get_parent_attribute needs to deal in Sentinel not None
* No need to special case any_errors_fatal in task.py any longer
* Handle more edge cases around Sentinel
* Use Sentinel instead of None in TaskInclude
* Update code to clarify the vars we are copying are class attrs
* Add changelog fragment
* Use a default of Sentinel for delegate_to, this also allows 'delegate_to: ~' now to unset inherited delegate_to
* Explain Sentinel stripping in _extend_value
* Fix ModuleArgsParser tests to compare with Sentinel
* Fixes for tasks inside of roles inheriting from play
* Remove incorrect note. ci_complete
* Remove commented code
* Fail on attrs that don't work for includes
* Prefix with VALID_ to make it more clear
* Sort keywords
* Remove unnecessary list
* Adjust dynamic/static checking
* Support 'apply' to apply attributes to included tasks
* Cannot validate args for task_include
* Only allow apply on include_
* Re-enable arg validation, but only for include_tasks and import_tasks
* s/task/ir/
* Add tests for include_ apply
* Include context with AnsibleParserError
* Add docs for apply
* version_added
* Add free-form documentation back
* Add example of free-form with apply
* Skip self._parent on dynamic, defer to grandparent for attr lookup
* Revert _inheritable
* Add tests for include inheritance from static blocks
Fixes#38037#36194
* when including statically, make sure that all parents were also included
statically (issue #16990)
* properly resolve nested static include paths
* print a message when a file is statically included
Fixes#16990
* Can be configured in the ansible.cfg for tasks/handlers individually
* If an included filename contains no vars or loops, it will be expanded
in-place as if it were marked as static
