* Ensure `allow_duplicates: true` enables to run single role multiple times(#64902)
* Changed return value in `_load_roles` . Fixes#64902
* Add changelog fragment
* Add an integration test for the issue
* Fix changelog generation error and integration test.
* Fix yaml syntax error in changelog fragment
* Don't ignore a duplicate host for an already processed include, assume that the repetition indicates a new include. Fixes#40317
* Add intg tests to ensure duplicate items in loop are not deduped
* Add note about relative indexing
* Prevent using action/local_action on includes and imports. Fixes#28822
* Use ModuleArgsParser to determine action instead of disallowing action/local_action with import/include
* Add to_native
* switch back to block in task_ds, use ModuleArgsParse otherwise
* var should be task_ds
* Add test validating action+include_tasks
* Add include_import tests for many top level include_tasks
Rename a few test playbooks to make more sense
* Use fewer include_tasks due to memory limits in CI
* Test for include_tasks & include_role bug
Related to ansible/ansible:#21890
* Fix nested include_tasks called from role
This fixes the path of included files when you want
to call include_task inside a role's task file and this
role is itself called from multiple level of playbook include_tasks

This fixes ansible/ansible:#35109
* First pass at include_role tests
* Reorganize test structure
Do all import and include tests in a single target.
* Build out more tests and test with linear and free strategy for each type
* import_role tests
* Set target host for play test
* Basic import_playbook tests
* Basic import/include_tasks tests
* Add recursion test
* import_playbook tests
* Add import_playbook group_vars test
Issue #33177
* Additional group_var tests for import_playbook
* Enable recursion test
* More work on import_tasks
* Run all tests via run.sh, improve conditional tests, add never tag
Add never tag to certain failining tests and explicitly skip it for now until #34104 is merged. Some tasks need to remain commented out because they cause the entire play to fail and aren't skippable by tags because they are syntax and/or variable checks.
Improve test for whether or not a role was run based on a conditional. Since the [import|include]_role does not register a variable, use a variable that is set inside a role as a canary test for whether or not the role was run.
* Use a fail task rather than trigger a failure via bogus command
This should resolve the "unstable" test results.
* Import tag tests
Fix bug it tests where validate tasks weren't run on tag tests.
Add tests for task import/include with tags.
* Remove test for playbook group_var inheritance
