Replace the commit semaphore in the segment node store with a scheduler

      Description

      SegmentNodeStore currently uses a semaphore to coordinate concurrent commits thus relying on the scheduling algorithm of that implementation and ultimately of the JVM for in what order commits are processed.

      I think it would be beneficial to replace that semaphore with an explicit queue of pending commit. This would allow us to implement a proper scheduler optimising for e.g. minimal system load, maximal throughput or minimal latency etc. A scheduler could e.g. give precedence to big commits and order commits along the order of its base revisions, which would decrease the amount of work to be done in rebasing.
