Sometimes multinode nodesets consist of nodes with private IPs from different L2 segments. So they can not communicate with each other using their IPs assigned to their gateway interfaces. This PR sets up VXLAN overlay using nodes inventory public IPs (those IPs used by zuul to get access to nodes). So nodes are convinced they are in the same L2 segment. We can use this overlay for internal K8s communication. For this we have to disable overlay setup in a CNI implementation (Calico, Cilium, etc.) and use the overlay interface for internal Openstack communication. Also: - Upgrade Kubeadm config API version to kubeadm.k8s.io/v1beta4 - Ignore single cpu kubeadm errors. By default Kubeadm requires at least 2 cpus on nodes.
