CLI support for displaying DOM threshold fields

[mihirpat1]

Description

This issue will track the progress for enabling support for dumping the required fields for TRANSCEIVER_DOM_THRESHOLD through 'show int transceiver eeprom threshold' CLI
Sample output of the CLI (the "show interfaces Ethernet4/21/1 transceiver detail" CLI will be changed to something else to be more specific to display DOM threshold values):

YQB20-0201-0100-03T2(s1)#show interfaces Ethernet4/21/1 transceiver detail 
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.

No since transceiver DOM sensor and threshold related changes are still pending. So far, we have completed CLI for transceiver info and PM.
