Description

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
