woopstar 86e3506ae6 Etcd cluster setup makeover
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
