> As proposed in YARN-914, a new state of “DECOMMISSIONING” will be added and can transition
from “running” state triggered by a new event - “decommissioning”. 
> This new state can be transit to state of “decommissioned” when Resource_Update if
no running apps on this NM or NM reconnect after restart. Or it received DECOMMISSIONED event
(after timeout from CLI).
> In addition, it can back to “running” if user decides to cancel previous decommission
by calling recommission on the same node. The reaction to other events is similar to RUNNING
state.
