* controlPlaneEndpoint set up through load balancer should be possible even in single master setups
Enable load balancer for single-master setups
Fixes an issue where single-master setups are not reachable using the usual admin.conf from outside the cluster.

* Add support for running a nodelocal dns cache
After encountering dns issues in a cluster I was recently working on I
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.
Introduced variable `ingress_nginx_tolerations` to set custom
tolerations for Ingress nginx daemonset, to be able to schedule
ingress-nginx on dedicated nodes with taints.
* Update defaults to match k8s 1.12 suggestions
* Test if Netchecker works with node ip instead of localhost
* Update defaults to ipvs and coredns
* Update defaults for kube_apiserver_insecure_port
* Update main.yaml
When `ansible_user` is not root, using `-b` option.
And with `download_run_once` and `download_localhost` set `true`.
Ansible will executes `container_download | upload container images to nodes` task.
It uses rsync to upload images to `/tmp/release/container/`, but the
`container` directory owned by `root`.
Now the `kubespray-aws-inventory.py` script always set a node_labels key
to ansible_host.
When AWS instance did not set property labels, it would be an empty
string.
The TASK `Write kubelet config file (kubeadm or non-kubeadm)` will
failed with a msg:
`AnsibleUndefinedVariable: 'unicode object' has no attribute 'items'`.

* Remove old metrics server clusterrole template
* Fix addon-resizer image specify
* Make InternalIP default for metrics_server_kubelet_preferred_address_types
Make InternalIP default because multiple preferrred address types does not work.
comparison that happens during `TASK [kubernetes-apps/ansible : Kubernetes Apps | Lay Down CoreDNS Template]` where the `dns-autoscaler` template is deployed causes coredns to fail deployment. The error is caused by the variable `dns_prevent_single_point_failure` where an integer is being compared with a string. The resulting error:
```bash
'>' not supported between instances of 'int' and 'str'
```
prevents successful deployment of CoreDNS.
The change makes the comparison happen between integers and allows CoreDNS to succeed.
* Enable AutoScaler for CoreDNS
* Only use one template for dns autoscaler
* Rename a few variables for replicas and minimum pods
* Rename a few variables for replicas and minimum pods
* Remove replicas to make autoscale work
* Cleanup kubedns-autoscaler as it has been renamed
add prometheus annotations to calico-node if
calico_felix_prometheusmetricsenabled is enabled.
This will allow a kubernetes_sd to automaticly find the pods and start
scraping.

* Converted ExecStop to ExecSTartPost. Removed the live restore check from the orphan script
* Adds support for Multus (multiple interfaces) CNI plugin
Multus is a latin word for "Multi". As the name suggests, it acts as a
Multi plugin in Kubernetes and provides multiple network interface
support in a pod. Multus uses the concept of invoking delegates by
grouping multiple plugins into delegates and invoking them in the
sequential order of the CNI configuration file provided in json format.
* Change CNI version (0.1.0->0.3.1) of Contiv to be compatible with Multus
When using resolvconf_mode host_resolvconf, there is an early DNS
config stage where Kubernetes cluster DNS is not injected for host
DNS intially. Later, the cluster DNS is enabled, but we do not
need to run every task from the kubernetes/preinstall role.
