Fix kubeapi cidr restrictions
Created by: chess-knight
It seems that from the 'namespace per cluster' feature #481, this was broken
Before, resources were inside the default namespace, so patching did work. But now we have an error
Error: no matches for Id OpenStackCluster.v1alpha7.infrastructure.cluster.x-k8s.io/testcluster.[noNs]; failed to find unique target for patch OpenStackCluster.v1alpha7.infrastructure.cluster.x-k8s.io/testcluster.[noNs]
