> Reduce the no. of rebuild operations and acquire/release by recognising when other size change actions are already queued and wait until they are finished before rebuilding state and asking AM for more nodes
> Appmaster Renew/Request/Release nodes operation to schedule a renewal via the queue; when that action is executed, to look in the queue for any queued cluster size change operations/events & place itself at back of queue if so. 
> If an existing renew operation is scheduled, do not queue a new one.
