      Adds option to disable master's attempt at recovering zookeeper session: i.e. just fail. Set the fail-fast option when you have a backup master running that you can fail to.

      Description

      When the active master's zk session expires, it'll try to recover zk session, but without turn off its RpcServer. What if a previous backup master has already become the now active master, and some client tries to send request to this expired master by using the cached master info? Any problem here?
