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.

* Tag win_nodes roles with master

* Dummy change

Update README with correct versions

README contains wrong versions. Let's fix that.

Due to suboptimal external loadbalancer configs, the LoadBalancer
might point to a downed kube-apiserver that is not set up yet.

* Update DNS Autoscaler to latest

* Update CoreDNS to latest

* Update KubeDNS to latest

* Add KubeDNS config map

* Fix filename

* Add missing selector to DNS Autoscaler

* Add missing tolerations

* 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

* weave: Upgrade to 2.5.0

Upstream Changes:

-   weave 2.5.0 (https://github.com/weaveworks/weave/releases/tag/v2.5.0)
-   Adds support for Kubernetes `hostPort` mapping
-   Adds support for Kubernetes `ipBlock` NetworkPolicy feature

Our Changes:

-   Templates sync with upstream manifests
-   Remove legacy nodePort fix

* BC for weave < 2.5.0

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.

* Revert netchecker image and version

* Create namespace for netchecker

* Remove extra slashes

Fix gen_tags.sh script

Set kubernetes node labels from a given comma-separated list of `key=value` from AWS instance tag `kubespray-node-labels`.

Use case is when kubespray runs from unprivileged user without sudo permission.

* Apply linux node selector to coreDNS deployment

* Remove comment before linux node selector on manifests

* mend

the ':' makes wrong return of calico_version after the calicoctl downloaded && before the cluster is up

* Update ha-mode.md

* Remove Vault

* Remove reference to 'kargo' in the doc

* change check order

if it tries to restart networking, as it is nonexistent.
