e40368ae2b Add CoreDNS support with various fixes
Added CoreDNS to downloads

Updated with labels. Should now work without RBAC too

Fix DNS settings on hosts

Rename CoreDNS service from kube-dns to coredns

Add rotate based on http://edgeofsanity.net/rant/2017/12/20/systemd-resolved-is-broken.html

Updated docs with CoreDNS info

Added labels and fixed minor settings from official yaml file: https://github.com/kubernetes/kubernetes/blob/release-1.9/cluster/addons/dns/coredns.yaml.sed

Added a secondary deployment and secondary service ip. This is to mitigate dns timeouts and create high resitency for failures. See discussion at 'https://github.com/coreos/coreos-kubernetes/issues/641#issuecomment-281174806'

Set dns list correct. Thanks to @whereismyjetpack

Only download KubeDNS or CoreDNS if selected

Move dns cleanup to its own file and import tasks based on dns mode

Fix install of KubeDNS when dnsmask_kubedns mode is selected

Add new dns option coredns_dual for dual stack deployment. Added variable to configure replicas deployed. Updated docs for dual stack deployment. Removed rotate option in resolv.conf.

Run DNS manifests for CoreDNS and KubeDNS

Set skydns servers on dual stack deployment

Use only one template for CoreDNS dual deployment

Set correct cluster ip for the dns server

Make sure output from extra args is strings
Setting the following:

```
kube_kubeadm_controller_extra_args:
  address: 0.0.0.0
  terminated-pod-gc-threshold: "100"
```

Results in `terminated-pod-gc-threshold: 100` in the kubeadm config file. But it has to be a string to work.

89847d5684 Explicitly defines the --kubelet-preferred-address-types parameter
to the API server configuration.

This solves the problem where if you have non-resolvable node names,
and try to scale the server by adding new nodes, kubectl commands
start to fail for newly added nodes, giving a TCP timeout error when
trying to resolve the node hostname against a public DNS.

b472c2df98 Fix safe upgrade
Even though there it kubeadm_token_ttl=0 which means that kubeadm token never expires, it is not present in `kubeadm token list` after cluster is provisioned (at least after it is running for some time) and there is issue regarding this https://github.com/kubernetes/kubeadm/issues/335, so we need to create a new temporary token during the cluster upgrade.

f57abae01e Remove redundant python-apt install
Ansible automatically installs the python-apt package when using
the 'apt' Ansible module, if python-apt is not present. This patch
removes the (unneeded) explicit installation in the Kubespray
'preinstall' role.
