Feat(eos_cli_config_gen): Add support for Receive Side Scaling (RSS) interface profile

[ashenoy-arista]

Add eos_cli_config_gen schema support for Receive Side Scaling (RSS) interface profile

Change Summary

Receive Side Scaling (RSS) interface profile schema to be later supported with jinja templates for generating EOS cli

Related Issue(s)

Fixes #4983

Component(s) name

arista.avd.eos_cli_config_gen

Proposed changes

Modeling the Receive Side Scaling (RSS) interface profile schema for eos_cli_config_gen
The associated CLI is supported on select hardware platforms namely -
CouncilBluffs platform - models AWE-5310 , AWE-7230R
Independence platform - models AWE-5510, AWE-7250R

There are two sets of CLI commands we need to target from schema perspective

1. Configuring one or more RSS profiles
2. Selecting one such profile for the system

Configure one or more RSS profiles

How to test

Ensure the generated EOS cli for RSS interface profile can be pasted without any error on supported hardware platform model such as AWE-5310 or AWE-5510
Please note, this needs feature-toggle "SfeRssCaravan" to be enabled on EOS device running latest trunk image (Jan 31 2025) => need to check with the team which EOS release this toggle will be enabled.

Pasted generated EOS cli with interface RSS profiles on supported platform such as CouncilBlufff AWE-5310-F
and issued "show run" and "show platform sfe interface profile" to validate output.

Currently unable to see newly added schema for eos_cli_config_gen under PR documentation link
https://ansible-avd--4954.org.readthedocs.build/en/4954/ansible_collections/arista/avd/roles/eos_cli_config_gen/docs/input-variables.html
Checking further how to resolve this.

Update: Resolved this issue after moving newly defined schema attributes under existing schema fragment file platform.schema.yml for eos_cli_config_gen

[ClausHolbechArista]

Looking good. Only a minor question on data model.
