Enable SMART metrics for IH

[yakimant]

Setup manually with:

--smartctl.device="/dev/sda;cciss,0"

Input from:

❯ lsblk --json -O | jq -c '.blockdevices[] | { path, hctl, subsystems }'
{"path":"/dev/sda","hctl":"2:1:0:0","subsystems":"block:scsi:pci"}
{"path":"/dev/sdb","hctl":"2:1:0:1","subsystems":"block:scsi:pci"}
{"path":"/dev/sdc","hctl":"2:1:0:2","subsystems":"block:scsi:pci"}

Or wait for auto configuration PR: prometheus-community/smartctl_exporter#274

Curtently adding --smartctl.scan-device-type=scsi will scan like that:

❯ sudo smartctl --scan -d scsi
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdc -d scsi # /dev/sdc, SCSI device

But scraping wil fail due to

/dev/sda: requires option '-d cciss,N'
