Breaking changes

various smartplugs, powerstrips, wall switches and dimmers that have a switch indicator light that can be set to different modes have been standardized to call the select entity "light_mode" with options "off", "on", "state", "locator". These all now have translations in all supported languages.
Goldair Platinum Tower Fan: the timer attribute has been removed from the climate entity. Use the timer number entity instead.
water_air heatpumps: these were abusing the operation_mode, so mode is now split out to a heat_pump_mode select entity, and operation_mode now only accepts "off" and "heat_pump".
