Expose drive speed and temperature on disk topo node
100%
Description
As part of the general effort to flesh out the hc-scheme topology, it would be nice if the drive speed and temperature were exposed on the disk topo nodes. Both speed and temp are available via libdiskmgt. Drive speed would be exposed as a uint32 topo prop directly on the disk node for non-SSDs. Drive temp would be exposed via a child sensor facility node.

Just a clarification that the temperature sensor requires support for the DKIOCGTEMPERATURE ioctl in the underlying driver. As such, this will work with SCSI-based devices, but not ATA/SATA, USB storage or NMVE. On those devices, the "facility/reading" property will fail to read.
Similar story for the speed-in-rpm property. It relies on underlying DKIO support in the driver.
