Coordinator that coordinates file compaction for the FileSink.

All committable emitted from the writers are collected and packed into CompactorRequests. The FileCompactStrategy defines when the requests can be fired. When a firing condition is met, the requests will be sent to the CompactorOperator.

The CompactCoordinator stores the non-fired committable as its state, and may emit a request at any time. A CompactorOperator must ensure that the ownership of the committable in a compact request is successfully handed from the coordinator, before it can actually perform the compaction.
