Add a way to disconnect the power to the board through GPIO #61

The idea is to provide a way to cut the power to the LibreRouter.

Like a self reset? or like suicide?

That functionality is already present through the watchdog that is also available at a GPIO.

This idea is to provide a way for an external board to use a GPIO ot cut the power of the board for longer periods of time. For example when connected to a solar panel and batteries in the night the LR can be turned on like for 2 minute each 10 minutes saving 80% of the battery power (even detecting if there is a station connected and keeping it on longer periods of time).

Ideally the voltage should be provided from the external source and the GPIO work from 3.3 to 24V.

Ok, so the GPIO is an external GPIO. image We can add there a PMOS transistor like: image with the same transistors that we are using for POE.
