Pull request overview

This PR adds VRF (Virtual Routing and Forwarding) association support to the vyos_interfaces resource module, updating the module schema, facts parsing, and test suites to ensure VRF configuration can be set/removed and correctly represented in structured data.

Changes:

• Extend vyos_interfaces argspec/module documentation to accept an interface-level vrf parameter.
• Update interfaces facts parsing to include vrf so state operations (replaced/overridden/deleted) can detect and remove VRF assignments.
• Add/extend unit + integration test coverage and fixtures to validate VRF set/remove/idempotency behavior.
