Description

OAK-7312 validated the feasibility of a strategy where cleanup runs before the compaction phase. Now that OAK-7377 and follow-up issues allow to define the garbage collection process in a more modular way, it should be relatively easy to introduce a new compaction strategy.

The new strategy shouldn't reduce the default compaction strategy. Instead, the new strategy should be hidden behind a feature flag in oder to exposes it to power-users for testing purposes.
