This is a massive overhaul to the SQL Storage for Authelia. It facilitates a whole heap of utility commands to help manage the database, primary keys, ensures all database requests use a context for cancellations, and paves the way for a few other PR's which improve the database.

no device is enrolled and see the standard 2FA method when a device is
already enrolled.
