Adding new members to fabric ensemble causes connections errors

Issue

When adding members to my ensemble, I'm seeing connection errors. The following are my steps:

FuseFabric:admin@root> container-create-ssh --host host002 --user host002 root2
FuseFabric:admin@root> container-create-ssh --host host003 --user host003 root3
FuseFabric:admin@root> ensemble-add root2 root3

Await provisioning success:

FuseFabric:admin@root> watch -n 1 container-list

Using a demo to that connects to my fabric, I see the following error message:

11:30:07 WARN Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.ConnectException: Connection refused

Using lsof -i you can see that the port 2181 has been replaced by 2182. Re-run the demo as a producer with port 2182 in the zookeeper.url and now you see:

11:40:33 ERROR javax.jms.JMSException: Could not connect to broker URL: discovery:(fabric:test-group).
