Allow Replication to be Enabled on Virtual Cluster

- Allow replication port assignment per NC.
- Allow replication to be enabled on virtual cluster.
- Wait for JOB_ABORT ACK from remote replicas.
- Fix LSM component mask file name.
- Fix index directory deletion on index drop.
- Eliminate multiple partition takeover requests.
- Free LogFlusher thread from sending replication ACKs.
- Fix possible deadlock between LogFlusher and Logs Replication Thread.
- Remove wait for FLUSH_LOG for replicated LSM components:
  This wait is not needed since on node failure, complete remote recovery is done.
