[Openshift] : 4.0.2-34: Single Yaml: Pod launch is failing

[chhandak]

On an Openshift cluster (brought up using Single Yaml) POD launch is failing. In /opt/cni/bin loopback binary was missing. Even after copying the same vrouter failed to fetch config in CNI log

Chhandak, after copying loopback binary to /opt/cni/bin, I noticed in your setup that the config did not have vRouter info. So I added the vRouters from the Contrail UI.

After this, the services are up. Please raise a separate bug for that & assign to Sachhin. I will fix the loopback issue in the playbook with this bug.
