migrator: Allow migrating between different configs of the same driver
This was notably a problem with SQL since mod_storage_sql is a single
module that connects to different SQL databases. The problem was that
since it was already loaded once, the output configuration was not
applied and it would have migrated to the origin database.
This essentially reloads the module after updating the configuration,
which should work with all storage modules as long as everything they
need are kept in the 'provider' or driver table.
