* 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
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* Warn on tests used as filters
* Update docs, add aliases for tests that fit more gramatically with test syntax
* Fix rst formatting
* Add successful filter, alias of success
* Remove renamed_deprecation, it was overkill
* Make directory alias for is_dir
* Update tests to use proper jinja test syntax
* Update additional documentation, living outside of YAML files, to reflect proper jinja test syntax
* Add conversion script, porting guide updates, and changelog updates

* Convert recent tests as filter changes to win_stat
* Fix some changes related to rebasing a few integration tests
* Make tests_as_filters_warning explicitly accept the name of the test, instead of inferring the name
