ARTEMIS-978 replicating live restarts as backup
In a cluster of replicated live/backup pairs if a backup crashes and
then its live crashes the cluster will retain the topology information
of the live such that when the live server restarts it will check the
cluster to see if its nodeID is present (which it will be) and then it
will activate as a backup rather than a live. To prevent this situation
an additional check is necessary to see if the server with the matching
nodeID is actually active or not which is done by attempting to make a
connection to it.
