Description

In repl load, update the status of target database to the last event dumped so that repl status returns that and next incremental can specify it as the event from which to start the dump. WIthout that repl status might return and old event which might cause, older events to be dumped again and/or a notification event missing error if the older events are cleaned by the cleaner.

While at it

• Add more logging to DB notification listener cleaner thread
  • The time when it considered cleaning, the interval and time before which events were cleared, the min and max id at that time
  • how many events were cleared
  • min and max id after the cleaning.
• In REPL::START document the starting event, end event if specified and the maximum number of events, if specified.
