Currently, if you try to use SASL-authenticated ZK with the ActiveStandbyElector, you run into a couple issues:
1) We hit
ZOOKEEPER-1437 - we need to wait until we see SaslAuthenticated before we can make any requests
2) We currently throw a fatalError when we see the SaslAuthenticated callback on the connection watcher
We need to wait for ZK-1437 upstream, and then upgrade to the fixed version for #1. For #2 we just need to add a case there and ignore it.
