Move replication znodes to pb
Convert zk root-region-server znode content to pb
Move clusterid and clusterup (shutdown) znodes over to pb
Move active master and backup master znodes to use pbs
Move SplitLogManager splitlog taskstate and AssignmentManager RegionTransitionData znode datas to pb
Convert rs, shutdown, and table dir content to pb
Here's whats up in zk as of trunk today:
[splitlog, unassigned, root-region-server, rs, backup-masters, draining, table, master, shutdown, hbaseid]
The 'rs' has nothing in it. Might add something. Leaves shutdown and content of table dir to do.
IMO, zk is all pb now so resolving.
