Superkaramba: add GPU load sensorr14.1.3

The sensor has a required `driver` parameter and an optional `gpu` parameter.
- The former specifies the backend to use to query the system about GPU load.
- The latter specifies the id of the GPU to check. If left out, the backend default will be used.

For now it only supports NVidia GPUs via the `nvidia` driver, but it can be extended.
