Description

In case of a JobManager restart, which can happen due to an uncaught exception, the JobManager is restarted. However, connected TaskManager are not informed about the disconnection and continue sending messages to a JobManager with a reseted state.

TaskManager should be informed about a possible restart and cleanup their own state in such a case. Afterwards, they can try to reconnect to a restarted JobManager.
