> When RM received a JM's registration, it will record it either with some
> leaderid or leadership listener. We should make sure the finished / failed JM
> can properly unregister itself with RM.
> We can make it happen by doing these two things:
> 1. If JM finds out job reaches a terminate state(either success or fail), it
> should send an unregistration request to RM.
> 2. If (1) does not happen for various reasons, RM can rely on the heartbeat
> manager to find out timeout JM and clear it up.
