> MIN_HISTORY_LEVEL table is used in two places:
>  * Cleaner uses it to decide if the files can be removed - this could be replaced by
adding a new column to compaction_queue storing the next_txn_id when the change was committed,
and before cleaning checking the minimum open transaction id in the TXNS table
>  * Initiator uses it to decide if some items from TXN_TO_WRITE_ID table can be removed.
This could be replaced by using the WRITE_SET.WS_COMMIT_ID.
