[CI] Remove OpenShift 4.7 CI clusters

We are removing support for OpenShift 4.7 since it reaches End of Support + 3 months in February 2022. Removing clusters we no longer support frees us up to launch newer versions of OpenShift for testing.

Use scripts/destroy_openshift_cluster.sh for cleanup of Google cloud cluster resources.
