Subject: Fix registry_auth logic for upgrades

Currently, the logic for registry authentication is
not implemented correctly to account for upgrades of
containerized hosts.

Additionally, the logic to account for multiple runs
of openshift-ansible might cause registry authentication
credentials to not be mounted inside of containerized hosts.

This commit adds the necessary logic to ensure containerized
hosts retain registry credentials.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1494470
