NVME temperature reporting

[erpalma]

Hello, It would be very useful if udisks supports reading the temperature of NVME drives. Right now the only way is to use smartctl or nvme which both lack DBus:

# nvme smart-log /dev/nvme0n1
Smart Log for NVME device:nvme0n1 namespace-id:ffffffff
critical_warning                    : 0
temperature                         : 39 C
available_spare                     : 100%
available_spare_threshold           : 10%
percentage_used                     : 0%
...
Warning Temperature Time            : 0
Critical Composite Temperature Time : 0
Temperature Sensor 1                : 39 C
Temperature Sensor 2                : 48 C
Thermal Management T1 Trans Count   : 0
Thermal Management T2 Trans Count   : 0
Thermal Management T1 Total Time    : 0
Thermal Management T2 Total Time    : 0

Isn't it part of the SMART data for the device? udisks already provides that.

This is probably duplicate of #386 Temperature is reported in the org.freedesktop.UDisks2.Drive.Ata interface but it doesn't work for NVME drives (the interface is missing).

@erpalma Can you please send output of udisksctl info --drive YOUR_DRIVE (completion should work for the drive name, or it should be visible in udisksctl info --block-device /dev/nvme0n1 property Drive). Thanks.

Here is the output of udisksctl info --drive Samsung_SSD_960_EVO_1TB_************:

Thank you. There is no Disk.ATA interface so this is definitely duplicate of #386. I'll try to look at the original issue again soon.
