    [FLINK-4373] [cluster management] Introduce AllocationID, ResourceProfile, and AllocatedSlot

    These classes are introduced as part of the cluster management rework (FLIP-6)
    
    The `AllocatedSlot` represents a slot on the TaskManager, reserved by a JobManager. Prior
to FLIP-6, all slots are always implicitly reserved by the JobManager at which the TaskManagers
register. With FLIP-6, slots are dynamically allocated - hence the AllocatedSlot.
    
    A `Slot` is then an `AllocatedSlot` used by the Scheduler/ExecutionGraph for a task deployment,
possibly sub-dividing the slot for slot sharing. It references the executed tasks, subslots,
and has fields determining whether the slot is in use or freed.
    
    After this pull request, `Slot`, `SimpleSlot`, and `SharedSlot` have a dual functionality
to support FLIP-6 and the current style.
