> There are two (or more) versions of leader election: DistributedLeaderElection, DistClusterControllerElection, and possibly others that I'm missing. This isn't good because if there's any code change required, it's very easy to miss doing it everywhere.
> In particular, this is causing metrics to not be unregistered on leader election because this was fixed in one place and not the other.
