> Per discussion in YARN-3334, we need filter out unnecessary collectors info from RM in
heartbeat response. Our propose is to add additional field for running apps in NM heartbeat
request, 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.
