Starting with OCP 4.20, the kubernetes/conformance test suite is no longer available in the openshift-tests binary, causing the OPCT
  kube-conformance plugin (10-openshift-kube-conformance) to fail when attempting to run Kubernetes conformance tests. This prevents provider
  certification workflows from completing successfully on OCP 4.20+ clusters.  

The root cause is that the kubernetes/conformance suite was removed from openshift-tests in OCP 4.20. The conformance tests are now only available
   through the OTE (OpenShift Tests Extended) k8s-tests-ext binary embedded in the hyperkube image.   

Affected Versions:
  - OpenShift Container Platform: 4.20+, 4.21+
  - OPCT: v0.6.0 and earlier
  - openshift-tests-plugin: All versions prior to fix  

Working Versions:
  - OpenShift Container Platform: 4.19 and earlier (suite still available)

      100% reproducible on OCP 4.20+ clusters

  1. Deploy an OCP 4.20 or 4.21 cluster (any provider)
  2. Install OPCT CLI (v0.6.0 or earlier)
  3. Run OPCT with the kube-conformance plugin:
  opct run --watch
  4. Observe the plugin 10-openshift-kube-conformance execution

  - Plugin 10-openshift-kube-conformance fails with error:
  suite "kubernetes/conformance" not found
  - OPCT certification workflow fails
  - Subsequent dependent plugins (20-openshift-conformance-validated, 80-openshift-tests-replay) continue running despite prerequisite failure,
  wasting execution time
  - Provider certification cannot be completed for OCP 4.20+ clusters

  - Kubernetes conformance tests should execute successfully using the k8s-tests-ext binary from the hyperkube image
  - Tests should be extracted dynamically at runtime
  - Backward compatibility with OCP 4.19 and earlier should be maintained
  - Failed plugins should stop execution of dependent plugins to save time

  Impact:
  - Blocks provider VCSP validation for OCP 4.20+ releases
  - Affects all cloud providers and platforms applying for VCSP Program or self-validation (Oracle offerings)
  - Critical for Partners validating on OCP 4.20
