Title: adjust unmerged backfill lfn

Trigger for this change is to write unmerged backfill to /store/unmerged instead of /store/backfill. Take this opportunity to adjust the LFN configuration, locking it down. Instead of configuring the LFN prefix, now only can specify if no backfill or backfill 1 or 2 are used.
