Add light presets common module to devices. (#907)

Adds light preset common module for switching to presets and saving presets.
Deprecates the `presets` attribute and `save_preset` method from the `bulb` 
interface in favour of the modular approach.  Allows setting preset for `iot` 
which was not previously supported.
