> The {{DefaultDispatcherRunner}} does not log when it gains and loses
> leadership. This can make it hard to understand the behaviour from Flink's
> logs because {{*DispatcherLeaderProcess}} can suddenly be stopped w/o knowing
> why. I suggest to improve the logging in the {{DefaultDispatcherRunner}} to
> make the logs easier to understand.
