Review Comment:
Could possibly increment a metric for this condition, although I'm not sure
how useful it would be. I think knowing that all of the external compactors and
compaction threads in the tservers are fully utilized, along with a backlog of
waiting compactions, is a more useful indication that more capacity is needed.
