This epic will ensure we are able to vizualise User Defined Network traffic using network observability Operator and CLI.

To run a UDN compatible cluster, use clusterbot with:

launch 4.17 gcp,techpreview 

Then create the following UDN:

apiVersion: k8s.ovn.org/v1
kind: UserDefinedNetwork
metadata:
  name: layer3-crd-network
  namespace: ns
spec: 
  topology: Layer3
  layer3:
      role: Primary
      subnets:
      - cidr: 10.10.0.0/16
        hostSubnet: 24 

Then create pods in your namespace and check for interfaces using:

ip a

A followup spike / epic will be created to cover improvement around UDN observability.
