> Per discussion in YARN-3334, we need filter out unnecessary collectors info 
> from RM in heartbeat response. Our propose is to add cache for runningApps in 
> RMNode, so RM only send collectors for local running apps back. This is also 
> needed in YARN-914 (graceful decommission) that if no running apps in NM 
> which is in decommissioning stage, it will get decommissioned immediately.
