[FLINK-8773] [flip6] Make JobManagerRunner shut down non blocking
## What is the purpose of the change
The Dispatcher no longer shuts down the JobManagerRunner in a blocking

Instead it registers the termination futures and calls the shut down of the
JobManagerSharedServices once all JobManagerRunners have terminated.
