Feat(config)!: Move new_mqtt_client out of global automation table into separate module

The function `new_mqtt_client` was the last remaining entry in the
global `automation` table. The function was renamed to `new` and placed
in the new `mqtt` module. As `automation` is now empty, it has been
removed.
