Thanks for the review @GJL. Merging this PR after Travis gives green light.
> Decouple Execution from actual slot implementation
> --------------------------------------------------
>
> Key: FLINK-8078
> URL: https://issues.apache.org/jira/browse/FLINK-8078
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Labels: flip-6
>
> 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}}.
