Description

The ResourceManager may tell the TaskManager to give a slot to a specific JobManager.
The slot allocation messages are fenced via (RmLeaderID, JobID, AllocationID, ResourceID).
The TM will ack the request (RmLeaderID,AllocationID) to the RM and then offer that slot to the JM. If not accepted by JM, the TM notifies the RM that the slot is in fact available.
