OVN to OVN-H migration seems broken

OVN to OVN migration went in via https://github.com/openshift/cluster-network-operator/pull/1584. Seems like its not working as expected on 4.12 and 4.13

Following annotations are not being added to the nodes post oc patch

k8s.ovn.org/hybrid-overlay-distributed-router-gateway-ip:
k8s.ovn.org/hybrid-overlay-distributed-router-gateway-mac:

Also Network pods needs to be restarted which doesn't seem so

Although CNO config part looks ok

defaultNetwork:
      ovnKubernetesConfig:
        egressIPConfig: {}
        gatewayConfig:
          routingViaHost: false
        genevePort: 6081
        hybridOverlayConfig:
          hybridClusterNetwork:
          - cidr: 10.132.0.0/14
            hostPrefix: 23

4.12 and 4.13

Always

1.Bring up OVN cluster
2.Migrate to OVN-H by following oc patch 

oc patch networks.operator.openshift.io cluster --type=merge -p '{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"hybridOverlayConfig":{"hybridClusterNetwork": [{"cidr": "10.132.0.0/14", "hostPrefix": 23}]}}}}}' 

Cluster seems not to be migrated successfully to ONV-H

Cluster should migrate to OVN-H runtime successfully
