Minor cleanup for the scheduler upgrade, not expected to fix the problem, but related. https://github.com/openshift/openshift-ansible/pull/7333 Our belief is that ansible is skipping these task for no apparent reason.
PR updated: https://github.com/openshift/openshift-ansible/pull/7333 Cause was stale openshift.common.short_version set by openshift_facts being used inside the lookup plugin for scheduler config.
