  2. [FLINK-8087] Decouple Slot from AllocatedSlot 

    This commit introduces the SlotContext which is an abstraction for the SimpleSlot
to obtain the relevant slot information to do the communication with the
TaskManager without relying on the AllocatedSlot which is now only used by the
SlotPool.

This closes apache#5088.

  3. [FLINK-8088] Associate logical slots with the slot request id 

    Before logical slots like the SimpleSlot and SharedSlot where associated to the
actually allocated slot via the AllocationID. This, however, was sub-optimal because
allocated slots can be re-used to fulfill also other slot requests (logical slots).
Therefore, we should bind the logical slots to the right id with the right lifecycle
which is the slot request id.

This closes apache#5089.
