noticed Kubernetes 1.13 introduced support for running a nodelocal dns
cache.
I believe this can usefull for more people.

* Set configure-cloud-routes=false as default if no network plugin is used
As configure-cloud-routes default value is `true`, so it need to be set to `false` when not required to avoid error messages like:
"Couldn't reconcile node routes: error listing routes: unable to find route table for AWS cluster"
on, for example, AWS installations that don't use cloud native routing.
* Update kube-controller-manager.manifest.j2
remove extra spaces
Introduced variable node_taints which can be set in inventory for
specific hosts or in group_vars, which generates --register-with-taints
command line argument for kubelet.
