LimitlessLED: Configurable fade-out behavior (#7369)

* Configurable fade-out behavior

Adds a per-group "fade" option with values of "out" (default) or "none".
By default, the lights are faded out when turned off, but this can cause usability issues when manually switching wall switches, since the bulbs turn back on at minimum brightness.

* Changed fade value from enum to boolean

* No need to fall back to default since voluptuous takes care of that.
