kube-ui [2] is deprecated and not actively maintained since long time.
Instead kubernetes dashboard [1] has lot of features and is actively
managed.
With this patch kube-ui is removed and kubernetes dashboard is added
and enabled in k8s cluster by default.
The kubernetes dashboard is enabled by default. To disable it, set the
label 'kube_dashboard_enabled' to False
