Feature: radio control (BT/WiFi/Broadband)

[amadeo-alex]

This PR:

• adds a RadioCommand allowing for turning on/off the radio devices available on system (BT, WiFi, Broadband)
• changes the CommandManager to match the update delay of SensorManager (this allows for commands to provide "real time" feedback of their state - in case of this feature, whether the given radio is on/off in case user switches it manually from the OS)

---

Noteworthy:

• this command works best as a "Switch" type as it'll provide feedback on user made changes (currently due to bug all commands start as "Button" type - PR with fix is in the works)
• turning off the WiFi radio might end up with some time wasted on "why my HASS.Agent is not working?!", don't ask ;)
