Review Comment:
Did all of this code move somewhere else? I assume it, or a replacement, is
still needed.

If this is no longer called, which I think it isn't, then we can remove.

Review Comment:
Need to create a follow-on issue, if one does not exist, to figure out how
to display compaction information now. There is a page for external
compactions, but it should likely be promoted to a more prominent position. It
also probably needs some summarization as to how many compactions are occurring
per table.
