Add X25519MLKEM768 TLS verification test for OpenShift 4.21

[kaleemsiddiqu]

Summary

Add automated testing for post-quantum cryptography (PQC) TLS support in OpenShift 4.21 control plane components.

Changes

1. New Step Registry Test

Created openshift-e2e-test-qe-pq-tls-verify step that verifies all control plane components negotiate X25519MLKEM768 as the TLS1.3 group:

• kube-apiserver (port 6443)
• etcd (port 2379)
• kube-scheduler (port 10259)
• kube-controller-manager (port 10257)

Location: ci-operator/step-registry/openshift/e2e/test/qe/pq-tls-verify/

2. Periodic CI Test for 4.21

Added weekly periodic test:

• Job: periodic-ci-openshift-release-master-ci-4.21-e2e-aws-ovn-pq-tls-verify
• Schedule: Weekly (168h interval)
• Platform: AWS
• Purpose: Ensure PQC TLS negotiation works correctly in all control plane components

Test Methodology

The test uses:

1. oc port-forward to connect to each control plane component pod
2. openssl s_client to perform TLS handshake
3. Verification that X25519MLKEM768 is negotiated
4. Fails if ANY component does not negotiate the expected PQC group
