> We should expose a region level metric that represents max refCount among refCounts of
all compacted store files under the region. For successful archival of compacted store files,
it is important for this metric count to be 0 eventually if not immediately. If it is >0
for a considerably high amount of time, it indicates some issue i.e. reader refCount leak
on some compacted store files and in such case, archival would not be successful.
