Set up e2e testing framework for `cri-o` runtime

[maiqueb]

• deploy a K8S cluster using a crio container runtime
• deploy multus on the cluster
  • deploying via CNAO is not an option - at least until CNAO tracks the thick plugin option. This is tracked in this PR.
• add multus daemon socket to the controller
• successfully provision the manifests on the examples directory

NOTES: kubevirtci runs the nodes as VMs within containers. This means we'd need to setup the github actions to have (at least) qemu. Not sure if emulating the kvm device would give enough performance to run the tests or not. More work is required...

We should probably give this github action a try instead of the kubevirtci approach: https://github.com/medyagh/setup-minikube
