Jube should allow to join existing ZooKeeper ensemble

eg maybe use a ENV variable to point to an existing ZK url to use to join existing ensemble. eg when you have more hosts of jubes and need them to join the ensemble.

I think this is fixed already (though it could use more docs and testing to ensure it really works ;)

Ah great, yeah it needs maybe a bit more detail in the startup process, and maybe a new doc page about how to configure jube with ZK
