I think I want to write out the GPU metrics too. The reason I say that is our gpu temp/fan speeds will stick at their current values unless those are...

 This is an example of what I mean. You'll see -1 for kinko2 but the temp is obviously "stuck".

TODO: add a write out for miner_gpu for number of gpus in conf file. Will write -1 for temp and fan speed.
