Description of problem:

We are missing the new logic for handling v6-primary in the VSphere UPI nodeip-configuration service: https://github.com/openshift/machine-config-operator/blob/ea88304dd6de521d55a9d3413a764f618af2425a/templates/common/vsphere/units/nodeip-configuration-vsphere-upi.service.yaml#L40
