Remove SmartPlug in favor of SmartDevice (#781)

With the move towards autodetecting available features, there is no reason to keep SmartPlug around.

kasa.smart.SmartPlug is removed in favor of kasa.smart.SmartDevice which offers the same functionality.
Information about auto_off can be accessed using Features of the AutoOffModule on supported devices.
