> 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.
