Addition of MQTT support

[teixeluis]

I'm sure this is a topic that may have came across the mind of several people looking into this and similar projects: would you consider relevant to enable MQTT for controlling at least the existing features. E.g.:

• Control the stream start/stop;
• Control the camera settings (brightness, contrast, etc);
• Turn the illuminator led on or off;
• Considering your wish-list of adding motion detection, publish a message to a configurable topic when motion is detected. Optionally add the URL of the captured image, to the MQTT message payload;
• Periodic status message with some system information such as Wifi RSSI, memory and cpu usage, esp32 chip internal temperature, etc;
• Reboot the camera;

Just looking for some feedback if this could make sense.

Thanks.

Cheers

As long as its optional at compile time I don't object. I won't be writing it though.

Fair enough :)
