Add test to assert cluster manager recovery.

Assert that when the cluster manager is killed and is restarted by the
supervisor, that all connections that should be established, are.

Assert this through configuring bidirectional replication and killing
the cluster manager on every node, in every cluster, and asserting that
connections are recovered.

This test verifies that the cluster locator name regression and patches
applied today for both 1.4.4 and develop ensure connections are 
reestablished after the process exists and is restarted by its supervisor.

This test also needs to be ported to the develop branch and added to 
GiddyUp for both releases.

This test also addresses the following issue 
https://github.com/basho/riak_repl/issues/349.
