> In order to support transparent "spanning" of jobs across sub-clusters, all AM-RM communications
are proxied (via YARN-2884).
> This JIRA tracks federation-specific mechanisms that decide how to "split/broadcast"
requests to the RMs and "merge" answers to 
> the AM.
> This the part two jira, which adds secondary subclusters and do full split-merge for
requests. Part one is in YARN-3666
