Chunk server: enforce stricter chunk delete rules by considering only the first meta data write op in the queue, in order to ensure that no stale / abandoned stable chunks exists when chunk server restarts. Given that single meta op can be in flight at a time, see if the front op is rename, and if it is, then use its stable flag and target version. Make status retrieval meta data op stricter by retrieving only status for the subset of events. Verify correctness of the delete queue entries.
