Expected output for transceiver DOM CLI

[mihirpat1]

Add the expected output for show interfaces transceiver dom <port> CLI for all types of transceivers.

Overall, this CLI will display the real time values and threshold data for the DOM sensors on the particular SFP. The CLI is planned to read data from TRANSCEIVER_DOM_SENSOR and TRANSCEIVER_DOM_THRESHOLD STATE_DB tables.

The current output is classified in 3 sections.
Section 1 will be displayed for all transceivers.
Section 2 will be displayed only if the transceiver is CMIS or C_CMIS based
Section 3 will be displayed only if the transceiver is C_CMIS based

@prgeor @qinchuanares @keboliu @shyam77git - It will be great if you can help in review this.

In PR sonic-net/sonic-utilities#2630 "show interfaces transceiver info {interface}" was added as a warper to "sfpshow eeprom -p {interface}", will this command be a similar case? a wraper to "sfpshow eeprom -p {interface} --dom"?

@keboliu We plan to deprecate "sfpshow eeprom" in future and use "show interfaces transceiver info {interface}" or "show interfaces transceiver dom {interface}" for dumping EEPROM info or DOM related information.
Currently, we plan to add "show interface transceiver dom {port}" as a wrapper to "sfpshow dom {interface}"
