The current way to setup the etc cluster is messy and buggy. - It checks for cluster is healthy before the cluster is even created. - The unit files are started on handlers, not in the task, so you mess with "flush handlers". - The join_member.yml is not used. - etcd events cluster is not configured for kubeadm - remove duplicate runs between running the role on etcd nodes and k8s nodes
