> improve node decommission latency in RM. 
> Currently the node decommission only happened after RM received nodeHeartbeat from the
Node Manager. The node heartbeat interval is configurable. The default value is 1 second.
> It will be better to do the decommission during RM Refresh(NodesListManager) instead
of nodeHeartbeat(ResourceTrackerService).
