[RFE] Add Host Metadata for GPU

[sadsfae]

For QUADS 2.0 / APIv3 we should collect GPU model/type hardware information. All normal compute servers will likely have an integrated GPU as part of the chipset (typically not used) but lshw will capture this.

"children" : [
                    {
                      "id" : "display",
                      "class" : "display",
                      "claimed" : true,
                      "handle" : "PCI:0000:03:00.0",
                      "description" : "VGA compatible controller",
                      "product" : "Integrated Matrox G200eW3 Graphics Controller",
                      "vendor" : "Matrox Electronics Systems Ltd.",
                      "physid" : "0",
                      "businfo" : "pci@0000:03:00.0",
                      "version" : "04",
                      "width" : 32,
                      "clock" : 66000000,
                      "configuration" : {
                        "driver" : "mgag200",
                        "latency" : "0",
                        "maxlatency" : "32",
                        "mingnt" : "16"
                      },

We just need to determine the relevant values we should capture, I think at a minimum product and vendor
