> 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.
