> When a task manager is no longer needed (e.g. due to idle timeout in slot manager), the RM should gracefully stop it without spurious warnings.   This implies some actions should be taken before the TM is actually killed.   Proactive steps include stopping the heartbeat monitor and sending a disconnect message.   
> It is unclear whether `RM::closeTaskManagerConnection` method should be called proactively (when we plan to kill a TM), reactively (after the TM is killed), or both.
