> ClusterNodeTracker should have a method to return the list of nodes matching a particular
resourceName. This is so we could identify what all nodes a particular ResourceRequest is
interested in, which in turn is useful in YARN-5139 (global scheduler) and YARN-4752 (FairScheduler
preemption overhaul).
