> Simple tweaks to make the logging less verbose during failover scenarios:
> - client should log a message before it sleeps for retry, including how long it plans
to retry and whether it will failover
> - server shouldn't log full stack trace when it throws StandbyExceptions, since they're
a "normal part of doing business"
