[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.

> Components: Cluster Management
> Reporter: Kurt Young
> Assignee: Kurt Young

> For the new version of cluster management, we need some more basic data
> structures:
> * SlotID: Identifier of one single slot located in a task executor
> * AllocationID: Slot allocation identifier, created by the JobManager when
> requesting a slot, constant across re-tries. Used to identify responses by
> the ResourceManager and to identify deployment calls towards the TaskManager
> that was allocated from.
> * ResourceProfile: The resource profile of the desired slot (currently only
> cpu cores and memory are supported
