> In QuorumCnxManager, the listener thread will exit if it cannot bind to the election
port after trying 3 times. Which will keep the server running but unable to join a quorum,
the process will be dangling there and only rejecting requests. It seems it's better to
exit instead of sitting there doing nothing.
