Feat (eos_cli_config_gen): Add support for dom-thresholds

[chetryan]

Enhancement summary

Add support for transceiver dom-threshold commands.

transceiver dom-threshold file <path to csv file>

Which component of AVD is impacted

eos_cli_config_gen

Use case example

transceiver dom-threshold file <path to csv file>

Describe the solution you would like

This is global configuration, so maybe something like [transceiver_qsfp_default_mode_4x10](https://avd.sh/en/latest/roles/eos_cli_config_gen/docs/input-variables.html##) might be useful, for example:

transceiver_dom_threshold_file: <path to file>

Describe alternatives you have considered

I am using eos_cli at the moment to add this command to the configuration.
