5f12b7aedf Remove kubedns and dnsmasq. Move dns_late phase after apps (#4406)
Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

e3dcd96301 kubedns & kubedns-autoscaler: Stick to master nodes. (#2909)
* kubedns & kubedns-autoscaler: Stick to master nodes.

 - Tolerate only master nodes and not any NoSchedule taint
 - Pods are on different nodes
 - Pods are required to be on a master node.

* kubedns: use soft nodeAffinity.

Prefer to be on a master node, don't require.

* coredns: Stick to (different) master nodes.

     - Pods are on different nodes
     - Pods are preferred to be on a master node.

0c6f172e75 Kubernetes Dashboard v1.7.1 Refactor
This version required changing the previous access model for dashboard completely but it's a change for the better. Docs were updated.

* New login/auth options that use apiserver auth proxying by default
* Requires RBAC in `authorization_modes`
* Only serves over https
* No longer available at https://first_master:6443/ui until apiserver is updated with the https proxy URL:
* Can access from https://first_master:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login you will be prompted for credentials
* Or you can run 'kubectl proxy' from your local machine to access dashboard in your browser from: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
* It is recommended to access dashboard from behind a gateway that enforces an authentication token, details and other access options here: https://github.com/kubernetes/dashboard/wiki/Accessing-Dashboard---1.7.X-and-above
