fan control

[akielaries]

Spend some time during a weekend to write something that controls the fans in the new RPI cluster case. They're pretty loud and ideally would either shut off the pis or the fans themselves after a certain time. Maybe this can be dynamic outside of the time range and a certain temperature could trigger them off. Either way make some progress on this as the number of devices is growing. Also come up with a quick way to provision every device to run sysd
