Feature Request: nvidia-smi support

[petrbel]

It would be nice to add a (optional) panel which would provide info about nvidia GPUs (e.g. workload memory, temperature etc).

The key functionality is already implemented in the nvidia-smi tool. Maybe it would be sufficient to add a panel in which nvidia-smi -l 1 runs and provides the info?

I wanted this too, so I implemented basic nvidia-smi support for GPU utilization in a fork. If any smi compatible cards are found, the grid size is increased and a 'GPU History' section is added at the bottom. Otherwise, the UI remains the same.

Give it a try if you like: https://github.com/jessemartin/gtop

It's also not difficult to display GPU memory utilization in addition; however, screen real estate is already scarce, so I've left that for someone more UX-minded to tackle :)

@jessemartin I am impressed! Great job. Hope #67 will be merged :)
