    Sorry, the commit message quotes the JIRA entry title. I'll change the message, but quote
the JIRA title in the body.

> ZKClusterCoordinator notifies listeners of type DrillbitStatusListener when drillbits
disappear from ZooKeeper. The YARN Application Master (AM) also needs to know when bits register
themselves with ZK. So, ZKClusterCoordinator should change to detect new Drill-bits, then
call DrillbitStatusListener.drillbitRegistered with the new Drill-bits.
