[FLINK-8078] Introduce LogicalSlot interface
## What is the purpose of the change
The LogicalSlot interface decouples the task deployment from the actual
slot implementation which at the moment is `SimpleSlot`. This is a helpful
step to introduce a different slot implementation for Flip-6.
## Brief change log
- Introduce `LogicalSlot`
- Replace `SimpleSlot` usage by `LogicalSlot`
- Let `SimpleSlot` implement the `LogicalSlot` interface
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.

[FLINK-8078] Introduce LogicalSlot interface
The LogicalSlot interface decouples the task deployment from the actual
slot implementation which at the moment is Slot, SimpleSlot and SharedSlot.
This is a helpful step to introduce a different slot implementation for
Flip-6.
