vyos_interface require multiple network nodes to run (#39670)

* vyos_interface require multiple network nodes to run

We don't have the ability to run these currently, so disable them.
The original logic was also incorrect, the tests don't pass on lab, DCI
nor single instance nodepool, so disable

https://github.com/ansible/ansible/issues/39667 tracks getting these
enabled again

* eth0 -> Gi0/0

* Correctly detect if we should run lldp
