OVN local mode breaks connectivity to pod services from hostnetwork pods. As a result metallb/sriov and several other operators don't work.

Set routingViaHost: true flag in following resource networks.operator.openshift.io cluster

Try to apply sriov or metallb policy and hit following error:

Internal error occurred: failed calling webhook "operator-webhook.sriovnetwork.openshift.io": failed to call webhook: Post "https://operator-webhook-service.openshift-sriov-network-operator.svc:443/validating-custom-resource?timeout=10s": context deadline exceeded

1. oc edit networks.operator.openshift.io cluster and set routingViaHost flag to true
  defaultNetwork:
    ovnKubernetesConfig:
      egressIPConfig: {}
      gatewayConfig:
        routingViaHost: true << This flag
2. Wait until the update is rolled out across all nodes 
oc get networks.operator.openshift.io cluster -o yaml

3. Try to apply sriov or metallb policy on cluster.

local gateway mode: routingViaHost-true flag breaks connectivity to pod services from hostnetwork pods

Local gateway mode should not break connectivity of hostNetwork pods
