Don't create ClusterOperator during precreation step if it's present in overrides

Using the installer, if a cluster operator is in overrides list, it is
still created during the precreation step.
When both the cluster operator and the deployment of an operator are
overridden, the CVO (and the installer) waits for ever the end of the
end of the provisioning.
