Missing smartctl flags

[intelfx]

I see from the code that it supports collecting a lot more metrics than the included smartctl call will generate. For instance, this is supposed to collect the ATA devstat log:

smartctl_exporter/smartctl.go

Line 445 in 3463e4f

for _, page := range smart.json.Get("ata_device_statistics.pages").Array() {

However, smartctl --json --info --health --attributes will never print it. There's also support for other log pages which, again, are absent in the smartctl output as invoked.

Consider switching to smartctl --xall.
