So far, this was only possible with a reduced set of variables to keep the database from growing forever. Recent database optimizations https://github.com/pi-hole/FTL/pull/1255 reduced the database size significantly allowing us to store more data in the database. This PR adds storing all the details necessary for the query log so a restart goes (almost) invisible and without any data loss. *) almost because some queries may not have been completed due to the forced restart and according service interruption.
