Display temperature-related statistics

Synopsis

nvme wdc vs-temperature-stats <device>

For the NVMe device given, displays temperature statistics.

The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).

This will only work on WDC devices supporting this feature. Results for any other device are undefined.

Expected status and description :-

Statistic	Description
The current composite temperature	device temperature
Warning Composite TEMPerature threshold	temp of overheating
Critical Composite TEMPerature threshold	temp of critical overheating
Device Initiated Thermal Throttling support status	0 = unsupported, 1 = supported
Host Controlled Thermal Management support	0 = unsupported, 1 = supported
Thermal Management Temperature 1 (Light throttle)	temp to start light throttle
Thermal Management Temperature 1 Transition Counter	# times switched into light throttle
Thermal Management Temperature 1 Total Time	# seconds spent in light throttle
Thermal Management Temperature 2 (Heavy throttle)	temp to start heavy throttle
Thermal Management Temperature 2 Transition Counter	# times switched into heavy throttle
Thermal Management Temperature 2 Total Time	# seconds spent in heavy throttle
Thermal Shutdown Threshold	temp of device shutdown

On success it returns 0, error code otherwise.

Displays the temperature stats for the device:
```
# nvme wdc vs-temperature-stats /dev/nvme0
```
