Override restart_on_change to add a random sleep time

119. By Liam Young on 2015-10-13

[tribaal, r=gnuoy] * Move log to a non-random time position (to have a chance at figuring out races)
* Added extra logging around leader-election or min-cluster-size.

[thedac,r=billy-olsen]

Ignore min-cluster-size when juju has leadership election.

This MP also addresses two major hurdles to rabbitmq clustering.

1) When more than one node has run stop_app at the same time
   nodes cannot join the cluster.

2) When using juju leadership election, if the elected leader
   is the third or greater node (i.e. rabbitmq/2 +), the leader
   would never be joined to the cluster.

Changing the clustering algorithm for each non-leader to join_cluster
with the leader resolves this. Also by clustering with the leader
rather than non-leader nodes we avoid split-brain clusters.
