[FLINK-4343] [tm] Implement TM -> JM registration logic Upon requesting a slot for a new job, the TaskManager registers this job at the `JobLeaderService`. The job leader service is responsible to monitor job leader changes for all registered jobs. In case of a new job leader, the service will try to establish a connection to the new job leader. Upon establishing the connection the task manager is informed about it. The task manager will then offer all allocated but not yet active slots to the new job leader.
