Steps to reproduce

1. Enable smartctl input

Expected behavior

The attribute metrics like smartctl_attributes_worst should use the name tag in the same way as the other metrics like smartctl_temperature, smartctl_power_on_hours use it, to identify the device by path, e.g. /dev/sda.

Actual behavior

Attribute metrics use the name tag for the attribute name. The device path does not appear anywhere in the tags.

Example (Prometheus output style):

smartctl_temperature{firmware="S0509A0",host="atom",model="TS240GMTS420S",name="/dev/sda",serial="sss",type="sat",wwn="nnn"} 62
smartctl_attributes_worst{host="atom",model="TS240GMTS420S",name="Valid_Spare_Block_Cnt",serial="sss",type="sat",wwn="nnn"} 100

Additional info

This makes it unwieldy to apply tag selection for related smrtctl metrics on the same dashboard, where the device name (path) is liable to be the primary, user-sensible selector for devices.
The device model number and serial number are available in tags for all metrics, but using these to link to metrics selected by device name is also unwieldy.

Edited: replace Prometheus "label" terminology with "tag".
