Description

In order to plug in a different slot implementation, we should introduce a slot interface which abstracts away the implementation details of SimpleSlot wrt Execution. The reason this is necessary is to provide a simpler slot implementation for Flip-6 since all allocation/release logic will go through the SlotPool. Thus, we no longer need the concurrent structure of Slot, SharedSlot, SimpleSlot and SlotSharingGroupAssignment.
