> The {{TaskExecutor}} should deregister jobs from the {{JobLeaderService}} once it no longer holds slots for this job. The problem is that before unregistering the job from the {{JobLeaderService}} in {{TaskExecutor#freeInternal}}, the actual slot is freed which also removes the {{JobID}} from the slot. Therefore, we lose the information to which job the slot belonged. An easy solution would be to return a {{SlotInformation}} object instead of the {{TaskSlot}} from {{TaskSlotTable#freeSlot}} which contains the respective information.
