Issue XD-1399: Admin leader should watch ZooKeeper for Stream deployment requests
The Stream deployment requests will be written to /xd/streams/streamname and the data on that node will include the state or a boolean indicator (for now) of whether it should be deployed. When a Stream is deployed, the leader will consult its Container cache and write the modules to the various /xd/deployments child nodes (see XD-1400).
