--------------------------------------------------------
[~mdrob] This is not going to make 2.0.0. Will have to be later. Notification
Bus will allow us an alternative to message-passing via ZK. It is incomplete.
We'll have to do w/ current mechanisms in meantime (of which we have a few --
smile).

> This is the third phase of Procedure V2 (HBASE-12439) feature. Built on top
> of state machine from Phase 1 (HBASE-14336), the notification bus is just
> an exchange of messages between the multiple machines (e.g. master and
> regionservers). The notification bus allows master to send
> notifications/procedures to the Region Servers. Two examples are snapshot for
> OnePhaseProcedure and ACL update for TwoPhaseProcedure (check HBASE-12439 for
> high-level design).
