--------------------------------------
Patch 2 removes the RMContainer from the RM on release, so that pending
releases don't need to be remembered.
> RM option to delegate NM loss container action to AM

> Currently, if the RM times out an NM, the scheduler will kill all containers
> that were running on the NM. For some applications, in the event of a
> temporary NM outage, it might be better to delegate to the AM the decision
> whether to kill the containers and request new containers from the RM.
