xref: #833

As a first step to GPU support, we want to avoid running scripts repeatedly and have something running that NPD can talk to over GRPC. I did some experiments in:
https://github.com/dims/npd-ext

Filing this PR as a first step. I've included a sample examples/external-plugins/gpu-monitor that just runs nvidia-smi.

NOTE that the protos are based off the same handshake that external plugins currently use. So this mechanism is NOT just for GPUs in any way.

Please see docs/external-plugins.md for more info.
