Description

Currently, the log level of granting/revoking leadership of JobMasterServiceLeadershipRunner is DEBUG. However, we usually configure it to INFO level in production jobs, which make it hard to understand the behaviour from Flink's logs because JobMasterServiceLeadershipRunner may suddenly be stopped. I suggest to improve the logging to INFO level.
