> As discussed HDFS-14961, ZKFC should not join election when its state is observer.
> Right now when namemode was an observer,  it joined election and it would be become a
standby.
> MonitorDaemon thread callchain is that
> doHealthChecks -> enterState(State.SERVICE_HEALTHY) -> recheckElectability() ->
elector.joinElection(targetToData(localTarget)) -> joinElectionInternal -> createLockNodeAsync
> callBack for zookeeper
> processResult -> becomeStandby
