Description of problem:

Even though in 4.11 we introduced LegacyServiceAccountTokenNoAutoGeneration to be compatible with upstream K8s to not generate secrets with tokens when service accounts are created, today OpenShift still creates secrets and tokens that are used for legacy usage of openshift-controller as well as the image-pull secrets. 

Customer issues:

Customers see auto-generated secrets for service accounts which is flagged as a security risk. 

This RFE is to track the feature for removing legacy usage and image-pull secret generation as well so that NO secrets are auto-generated when a Service Account is created on OpenShift cluster.
