During and install of 3.11 latest, the task 'openshift_control_plane : Report control plane errors' fails as the control plane pods did not come up[1]. The openshift-sdn namespace does not exist and we see the node service fails to come up due to CNI issues[2]. Looking in the api/controller logs(sosreport-ip-10-31-217-33-02416046-2019-06-28-jbriqyw/sos_commands/origin/*), we do not really see much indicating an unhealthy controller or api. 

Version:
atomic-openshift-3.11.98-1

Steps to reproduce:
[ ] Run installer https://docs.openshift.com/container-platform/3.11/install/running_install.html#running-the-advanced-installation-rpm
[ ] Playbook fails in task 'openshift_control_plane : Report control plane errors'

Expected Results:
[ ] Cluster installed with healthy control plane.
