Add support for CRI-O runtime interface

[msmith93]

I would like to use illuminatio to test my k3s cluster that is using CRI-O as the runtime interface, but it looks like it is not supported:

illuminatio --kubeconfig /etc/rancher/k3s/k3s.yaml clean run
Starting cleaning resources with policies ['on-request', 'always']
Finished cleanUp
Starting test generation and run.
