Cilium Connectivity Check Verifier into E2E tests using Cilium CNI plugin

[mbukatov]

https://redhat.atlassian.net/browse/ARO-25876

What

Add Cilium Connectivity Check Verifier into E2E tests using Cilium CNI plugin.

Why

To make sure Cilium CNI fully works.

Testing

We need to inject some errors during test development to make sure the verifier will detect and report them.

Special notes for your reviewer

See cilium/examples/kubernetes/connectivity-check:

• Set of deployments that will perform a series of connectivity checks via liveness and readiness checks.
• An unhealthy/unready pod indicates a problem.
• Suggested in validation section of HyperShift notes about cilium (with example of SCC for OCP)

Extra care should be taken to make sure failures are actually reported in a way to indicate which check failed.
