-----------------------------------------------------------
Currently, aurora_executor sends the task status update to scheduler, whereas
the health checker performs the health check. When a successful required number
of health checks is reached, the health checker needs to notify the
aurora_executor about the state change.
To solve this problem, we can implement a event-listener in aurora executor
that listens to a "TASK_RUNNING_TRANSITION" event dispatched by health checker.
Here is an example for the implementation of event dispatcher and event
listener: http://code.activestate.com/recipes/577432-simple-event-dispatcher/
