J. Nick Koston	https://github.com/bdraco	Deprecating all magic numbers for supported features

As of Home Assistant Core 2024.1, all usage of magic numbers for supported features is deprecated, and each entity platform has provided an EntityFeature enum to replace them.

There will be a one-year deprecation period, and the magic numbers will stop working in 2025.1 to ensure all custom integration authors have time to adjust.

This applies to, the following platforms:

• Alarm Control Panel

  Use the new AlarmControlPanelEntityFeature enum instead.

• Camera

  Use the new CameraEntityFeature enum instead.

• Cover

  Use the new CoverEntityFeature enum instead.

• Climate

  Use the new ClimateEntityFeature enum instead.

• Humidifier

  Use the new HumidifierEntityFeature enum instead.

• Fan

  Use the new FanEntityFeature enum instead.

• Light

  Use the new LightEntityFeature enum instead.

• Lock

  Use the new LockEntityFeature enum instead.

• Media Player

  Use the new MediaPlayerEntityFeature enum instead.

• Remote

  Use the new RemoteEntityFeature enum instead.

• Siren

  Use the new SirenEntityFeature enum instead.

• Vacuum

  Use the new VacuumEntityFeature enum instead.

• Water Heater

  Use the new WaterHeaterEntityFeature enum instead.
