Feature - Check if device is compatible through eureka endpoint

[DurgNomis-drol]

Actually even if the devices returns a 200 for eureka_info, there is no guaranty that the device supports alarms or timers, we still would need to check assistant_supported. This can also come in handy in the future where we can check what other features is supported.

The check should probably be a combination of both like this:

1. Request eureka_info if 404 return device not compatible. Else continue check.
2. Check if assistant_supported is true, return device is compatible. If false return device is not compatible.

eureka_info example:

If eureka_info is 200, we should create device sensor. If assistant_supported is true we should also create alarms and timers sensors and do not disturb switch.

Great idea! That exactly what i was thinking in earlier discussions, we could probably take a step backwards and implement it in the following manner:

• Request devices from foyer (glocaltokens)
• Initialize GoogleHomeDevice as we currently do in model per device
• Do eureka call to populate GoogleHomeDevice objects with necessary information (like capabilities) etc. (that can be expanded over time i guess
• Initialize HA sensors/services based on those object arguments stated in GoogleHomeDevice objects

yup also the reboot device function can be based on reboot_supported. A stub for future Bluetooth work based on ble_supported.
