Has anyone been able to extend the SQLLab Query History so it shows all the history of the query, not just the session for when it's open in the browser?  I have a requirement to enable Superset to show all the hisotry of the query, to provide an audit trail.  I saw a few settings in config.py for it (i.e.: def QUERY_LOGGER), and sql_lab.py (i.e.: result_backend) but not sure how to use them.
