Refactor parse_virtium_info to support new ssd model VTSM24ABXI160-BM110006

[yuazhe]

Description

The ID of "Remaining Life Left" attribute on 'Virtium VTSM24ABXI160-BM110006' device is 231.
However, it is not recognized by SmartCmd nor smartctl so far so we need to parse it using the ID number.
Also add a unit for this model

Motivation and Context

The Virtium prefix of the device model is shown from smartctl output, so keep it.

How Has This Been Tested?

unit test and real hardware test
show platform ssdhealth
Device Model : Virtium VTSM24ABXI160-BM110006
Health : 100.0%
Temperature : 52C

Additional Information (Optional)

Consider:

Refactor this function so that:

first check if current disk is one of the special Virtium SSD models, if so:

parse attribute 231 directly and exit

else (all other Virtium models) :

check for presence of NAND endurance and Avg erase count in the output

if present: get health that way
else: health = N/A

What do you think?
