[CI] Remove OpenShift 4.6 CI clusters
As discussed in #360 (comment 727035400), we are removing support for OpenShift 4.6 since it has reached End of Support + 3 months in September 2020. Removing clusters we no longer support frees us up to launch newer versions of OpenShift for testing, like 4.9.
To be removed:
-
4.6 .gitlab-ci.yml
configuration -
public OpenShift 4.6 cluster -
dev OpenShift 4.6 cluster -
Google cloud cluster resources, use scripts/destroy_openshift_cluster.sh
for cleanup -
KUBECONFIG_OCP_4_6
CI variables in this project -
OpenShift 4.6 kubeconfig and kubeadmin password entries in 1Password cloud-native vault -
Anything in the operator project referencing 4.6
