Add NVME Temperature Monitoring

[jmachuca77]

If the Jetson has an NVME installed it would be nice to be able to see the temperature from the NVME. We are having an issue with a custom carrier board where the NVME is overheating. NVME-CLI seems to have a solution for reading the temp out.

I have not found a real alternative for reading out the temperature in realtime.

Hi @jmachuca77

It's a feature that I was also thinking of adding on jtop, but the documentation on NVME devices is not clear! There are libraries available but not in Python, or the licensing doesn't permit me to use it.

I couldn't find any official documentation to manually read these values from the OS, so I couldn't create my personal driver. If you know references let me know.
