Problem
ancient append vec packing is now running at a reasonable interval (similar to when clean runs). As a result, we should now log the metrics each time it completes. It is not uncommon for ancient append vec packing to do nothing. In those cases, we still need to log how much time the algorithms spent trying to pack.
Summary of Changes
Log each time ancient append vec packing runs.
