openmds: issue a health warning with estimated time to complete replay
0%
Description
When the MDS is in up:replay, it does not give any indication to the operator when it will complete. We do have this information though. The MDS knows the end of the journal, the write position, and how quickly it's consuming (replaying) events. Issue a periodic health warning with the current completion percentage (e.g. 40% of journal read), time spent in replay, and expected time remaining.

Patrick, the "MDS behind trimming" warning during up:replay is kind of expected in cases where there are lot many journal events/segments to replay. I think it makes sense to have this warning show up when the MDS is up:active and during up:replay the MDS could warn for longer replay times depending on the expected replay completion time/percentage.

Sorry I'm not understanding where "MDS behind trimming" warning fits into this particular issue (beyond causing longer replay).

If "this warning" meaning "MDS behind on trimming", I think we're on the same page.
