> If external systems like ATS, or ZK becomes very slow, draining all the events take a
lot of time. If this time becomes larger than 10 mins, all applications will expire. Fixes
include:
> 1. add a timeout and stop the dispatcher even if not all events are drained.
> 2. Move ATS service out from RM active service so that RM doesn't need to wait for ATS
to flush the events when transitioning to standby.
> 3. Stop client-facing services (ClientRMService etc.) first so that clients get fast
notification that RM is stopping/transitioning.
