Add timeout and on duplicate to system tasks (#16169)

Modify the invocation of @task_awx to accept timeout and
on_duplicate keyword arguments. These arguments are
only used in the new dispatcher implementation.

Add decorator params:
- timeout
- on_duplicate

to tasks to ensure better recovery for
stuck or long-running processes.
