This PR is for problems discovered with Consul clustering as part of debugging #71.
The Consul server was continually trying to join itself because I switched it to use autopilotpattern/consul when it's only a single-node cluster.
Also, when we reload the config for the primary, the logic in manager/containerpilot.py includes the port 8500 in the
-retry-joinfield which it should not. So we join Consul just fine and then keep trying to re-join on a port that doesn't work after the reload.cc @misterbisson @jasonpincin @mbbender
