Description of problem: https://github.com/openshift/origin/blob/45d2bb293b4f6f8f053591c67b0ead39fbb9bb24/pkg/cmd/server/apis/config/v1/types.go#L528 In master config, section "networkConfig", HostSubnetLength and ClusterNetworkCIDR and deprecated in favor of ClusterNetworks. We need to ensure that ClusterNetworks is added to exisitng config files, it does not appear we have ever injected this setting previously for older clusters.
