* clear_notification method and simplify ifs
* Deduplicate code
* Limit number of Templar creations
* Fix sanity
* Preserve handler callbacks order as they were notified
* Make undefined variables in handler names non-fatal if the handler is not used
* If the handler has no way to be notified (i.e. the name can't be templated and the handler has no listen topics), display a warning
* Add tests for variables in handler names
* changelog
* Fix notifying handlers by using an exact match rather than a string subset if listen is text rather than a list
* Enforce better type checking for listeners
* Share code for validating handler listeners
* Add test for handlers without names
* Add test for templating in handlers
* Add test for include_role
* Add a couple notes about 'listen' for handlers
* changelog
* Add a test for handlers without names
* Test templating in handlers
* changelog
* Add some tests for include_role
* Add a couple notes about 'listen' for handlers
* make more sense
* move local function into a class method
* Ensure that include_role properly fires handlers
include_role needs to ensure that any handlers included
with the role are added to the _notified_handler and
_listening_handler lists of the TaskQueueManager, otherwise
it fails when trying to run the handler.
Additionally, the handler needs to be added to the
PlayIterator's `_uuid_cache` or it fails after running
the handler
Add more uuid debug statements - this code was hard
to debug with existing debug statements, so add more
uuid information at little additional output cost.
Fixes#18411
* Add tests for include_role handlers
Tests for #18411
This change corrects problems reported by the `yamllint` linter.
Since key duplication problems were removed in 4d48711, this commit
mainly fixes trailing spaces and extra empty lines at beginning/end of
files.
