Refactor(cv_deploy): Add support for new studio_topology API

[ClausHolbechArista]

Change Summary

Add support for new studio_topology API

Component(s) name

arista.avd.cv_workflow
arista.avd.cv_deploy

Proposed changes

• Add support for new studio_topology resource API but still prefer the legacy studio inputs api for topology studio.
• Later we will flip the preference based on versions and later again remove the legacy api for later versions.

How to test

Tested manually on CVaaS.

• Expecting no behavioral changes.
• Checked log messages for old and new api (try old, fail old, try new)
• Tested with molecule cv_workflow.

Requires flipping an alpha toggle per tenant, and after flipping it the backend needs to migrate data before the new API works. So avoid flipping back and forth.
