enable CONFIG_NVME_HWMON

Use case

Enable CONFIG_NVME_HWMON for monitoring of NVMe drives.

Describe the solution you'd like

CONFIG_NVME_HWMON exposes /sys/class/nvme/nvme0/device/hwmon which enables easier monitoring of NVMe drive health, including from unprivileged containers.

Hey @erkki -- this is a good point, but how do you envision using those? I mean, EVE then would have to export this somehow to the controller, right?

[erkki]

Our current thinking is to deploy a monitoring container that exposes a scrapeable interface (for other VMs etc to consume).

CONFIG_NVME_HWMON would enable this container to not be a privileged container (which currently works in tandem with nvme-cli)

This makes sense @erkki -- would you do the honors by sending us a PR? ;-)

[erkki]

Yes, let me take a look :)
