This request is to backport the RFE of which this is a clone of, to OSP 10.

I have tested this backport on OSP10 - seems to work:

$ openstack baremetal introspection start controller-0
$ openstack baremetal introspection data save controller-0 | python -m json.tool
...
       "disks": [
            {
                "by_path": "/dev/disk/by-path/pci-0000:00:08.0",
                "model": "",
                "name": "/dev/vda",
                "rotational": true,
                "serial": null,
                "size": 32212254720,
                "vendor": "0x1af4",
                "wwn": null,
                "wwn_vendor_extension": null,
                "wwn_with_extension": null
            }
        ],
...

installed latest OSP10

$ cat /etc/yum.repos.d/latest-installed 
10   -p 2018-08-04.1
