> In Yarn Federation, we use Yarn Registry to use the AMToken for UAMs in secondary sub-clusters.
Because of potential more app attempts later, AMRMProxy cannot kill the UAM and delete the
tokens when one local attempt finishes. So similar to the StateStore application table, we
need ApplicationCleaner in GPG to cleanup the finished app entries in Yarn Registry.
