> 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
