For clusters that are installed as fresh 4.15 o/installer will propagate Infrastructure.Spec and Infrastructure.Status based on the install-config. However for clusters that are upgraded this code in o/installer will never run.

In order to have a consistent state at upgrade, we will make CNO to propagate Status back to Spec when cluster is upgraded to OCP 4.15.

As we have already done it when introducing multiple VIPs (API change that created plural field next to the singular), all the necessary code scaffolding is already in place.
