Description

HBASE-2694 did a good bit of reworking around ZK, and removed/changed some pieces that were needed for replication to work correctly. Mainly 2 things:

• listZnodes needs to offer a version that takes a Watcher, else registering yourself as a listener is too much of a pain since you then filter a lot of stuff based on the path of the event/
• A lot more important, the new Multiton implemented in ZKW prevents from starting multiple clusters inside the same JVM since both masters would use the same "name".

I will provide a patch for both issues.
