addons: Update CLUO to fix compatability with Kubernetes 1.9

* Update CLUO from v0.4.1 to v0.5.0
* Earlier versions of CLUO fail to drain nodes on Kubernetes 1.9
so nodes drain one at a time repeatedly and Container Linux OS
updates are not applied to nodes.
* Check current OS versions via `kubectl get nodes --show-labels`
