I remember I commented in Jira ZOOKEEPER-3157, not sure why it didn't show
up.
I mentioned that we still need RetryRule, because there might be temporary
quorum unstable issues like what we found on our test environment. The quorum
set up in the test might be down due to leader election in case there is heavy
load/limited resources on that test environment. We have seen this happened
internally, so it's better to have retry for ConnectionLoss in this case.
