Functionally this is much better than before. Now when running clustered
and we start losing nodes we are able to see the current cluster participation.
However, once we have lost the quorum we are no longer able to update the
Primary Node. This behavior is expected, however. Once the quorum is
re-established the Primary is updated accordingly. As we move towards zero
master clustering, when there is no quorum we will return appropriate response
codes.
Looks good. Thanks!

> Currently, nodes send heartbeats to the NCM periodically in order to indicate
> that they are actively participating in the cluster. As we move away from
> using an NCM, we need these heartbeats to go somewhere else. ZooKeeper is a
> reasonable location to push the heartbeats to, as it provides the HA that we
> need
