Add support for NVME drives

[jwillikers]

Thanks for making this snmpd integration. Would it be possible to add support for NVMe devices? The smartctl output for NVMe drives is completely different than for SATA disks, so the parsing fails and just returns the max gauge counter value for all of the attribute fields.

[HackingM]

You're very welcome. I do intend to add support for NVMe devices in the very near future. Unfortunately some family issues are preventing me from working as much as I'd like at the moment. Hopefully I'll get some time soon.

One of the barriers to implementing this is that I only have access to drives from a single vendor. If you could post the output of smartctl -a /dev/nvmeX for each vendor's drives that you have access to that would be much appreciated.

I can definitely do that.

Okay, I grabbed all of the drives I've got available right now.
