``light.on_state`` Trigger

This trigger is activated each time the set light state is changed. It is not triggered
This trigger is activated each time the set light state is changed. It is not triggered
based on current state, but rather, it triggers on the set state which can differ from
the current state due to transitions. For example, the ``light.on_state`` trigger can
be used for immediate action when the light is set to off; while ``light.on_turn_off``
be used for immediate action when the light is set to off; while ``light.on_turn_off``
does not trigger until the light actually achieves the off state.
