Moving from pynvml to nvidia-ml-py

[jakirkham]

Currently this is making use of pynvml in a few places:

docs/deployment/nightly/_sources/cloud/azure/azure-vm-multi.md.txt

Lines 57 to 60 in 8540331

	import pynvml
	pynvml.nvmlInit()
	return pynvml.nvmlDeviceGetName(pynvml.nvmlDeviceGetHandleByIndex(0))

docs/deployment/stable/_sources/guides/mig.md.txt

Line 33 in 8540331

Alternatively, MIG instance names can be obtained programatically using [NVML](https://developer.nvidia.com/nvidia-management-library-nvml) or [PyNVML](https://github.com/gpuopenanalytics/pynvml). Please refer to the [NVML API](https://docs.nvidia.com/deploy/nvml-api/) to write appropriate utilities for that purpose.

However we would like to move to nvidia-ml-py in the future. Raising this issue to track this work
