    Description

      Add the ability to scale the RM-NM heartbeat interval based on node cpu utilization compared to overall cluster cpu utilization.  If a node is over-utilized compared to the rest of the cluster, it's heartbeat interval slows down.  If it is under-utilized compared to the rest of the cluster, it's heartbeat interval speeds up.

      This is a feature we have been running with internally in production for several years.  It was developed by nroberts, based on the observation that larger faster nodes on our cluster were under-utilized compared to smaller slower nodes. 

      This feature is dependent on YARN-10450, which added cluster-wide utilization metrics.
