Fix zuul settings to use latest kuryr-kubernetes

kuryr-kubernetes patch [1] that changes to use kubeadm for
installing Kubernetes on devstack.

A patch [2] was previously created to address the change, but the fix
used kuryr-Kubernetes stable/wallaby as a temporary fix.

This patch fixes to use latest kuryr-kubernetes.

* Change the ".zuul.yaml" setting to use the latest kuryr-kubernetes.
* Add the process of creating a ServiceAccount and change the vim
  authentication method to bearer_token. This is because
  kuryr-kubernetes does not create an admin ServiceAccount by default.
