leds and gpio access for snaps

[Joe Talbott]

What is the plan for snaps being able to access leds and gpio pins?
Will this be handled by an apparmor profile?  I am currently trying to
blink the leds on my BBB and I had to change my app's apparmor profile to
allow writes to /sys/devices/leds/leds/beaglebone\:green\:usr2/brightness
as well as change the permissions on it to allow the ubuntu user to write.

Thanks,
Joe
