Description

Implement a new SlotPool that works with declarative resource management.

It receives slot offers from the task executors and matches them against the requirements by jobs.

We will also require a compatibility layer that allows the new implementation to be used as a drop-in replacement for the current one.

Since we are not writing a new implementation this is also a good opportunity to split the implementation into several components, as it has grown quite large.
