Adding other Redhat's certified CNI plugins to e2e tests

[alibo]

I'd like to share the idea of testing other Redhat's certified CNI plugins in e2e tests (especially for the upgrades):

https://access.redhat.com/articles/5436171

for example, cilium supports Openshift and OKD and it also has its own testing tools (which can be used in the e2e tests)

• https://docs.cilium.io/en/v1.10/gettingstarted/k8s-install-openshift-okd/
• https://github.com/cilium/cilium-olm/
• https://github.com/cilium/cilium/tree/master/examples/kubernetes/connectivity-check

WDYT?

I don't mind setting up CI jobs if we find someone to look after these and fix issues

I wish I could do it, but apparently, your company doesn't allow me to contribute! so I hope you can find someone else :)
