> Right now it's a pain if you remove a peer and still have rogue queues because they get
moved on and on and on. NodeFailoverWorker needs to run the check:
> bq. if (!zkHelper.getPeerClusters().containsKey(src.getPeerClusterId())) {
> before this:
> bq. SortedMap<String, SortedSet<String>> newQueues = zkHelper.copyQueuesFromRS(rsZnode);
> And test.
