> ActiveStandbyElector retries operations for a few times. If the ZK quorum 
> itself is down, it goes down and the daemons will have to be brought up 
> again. 
> Instead, it should log the fact that it is unable to talk to ZK, call 
> becomeStandby on its client, and continue to attempt connecting to ZK.
