[arm-allstar] Feature request for single shutdown and boot gpio setup button switch.

[kd4ont]

I found, through lots of digging, that there is a default boot switch, with the gpio, with rp3. The suggested shutdown pin config, uses different pins. In my setup, I had to change the gpio pins to have two switches. I am not a python programmer yet. Could an update change this so that one pair of gpio and ground, if held for 6 seconds or less would make a graveful shutdown, yet, if the pi is off, a quick press would tell it to boot? This woukd free up a pair of pins and have less hardware to do the same thing. It would act just like a pc with a single power button. It seems more efficient to me. 
I don't know how many users might think this is a good feature request. One less hardware button. One less hardware software config. Just trying to think of streamlining ideas...
