Description

ChangeDispatcher should move from SegmentNodeStore to TarRevisions. With this change we should be able to remove the additional tracking of the head state in SegmentNodeStore and fully rely on the TarRevisions instance. The commitSemaphore and refreshHead method would disappear from SegmentNodeStore as they would be now implementation details of TarRevisions.

AFAIK, this is the last missing piece to be able to replace the commit semaphore with a real scheduler (OAK-4122).
