Upgrade Kubernetes to V1.11.2
The kubeadm configuration file version has been upgraded from v1alpha1 to v1alpha2
Add bootstrap kubeadm-config.yaml with external etcd

Use helm install or support in future

Upstream Changes:

-   weave 2.4.0 (https://github.com/weaveworks/weave/releases/tag/v2.4.0)
-   Support `externalTrafficPolicy: Local` (https://github.com/weaveworks/weave/issues/2924)
-   Make the ipset list size bigger (https://github.com/weaveworks/weave/pull/3305)
-   Break out of kube rm-peers loop if nothing changes (https://github.com/weaveworks/weave/pull/3317)

Our Changes:

-   Revamp weave-net.yml.j2 with upstream changes
-   Add more variables for customization
-   Replace WEAVE_PASSWORD with k8s secret
-   Remove hard-corded seed mode support, in favor of variables customization

ingress-nginx 0.16.2 (https://github.com/kubernetes/ingress-nginx/releases/tag/nginx-0.16.2)

This patch simplify ingress-nginx deployment by default deploy on
master, with customizable options; on the other hand, remove the
additional Ansible group "kube-ingress" and its k8s node label
injection.

Reference to https://kubernetes.io/docs/concepts/services-networking/ingress/#prerequisites:

    GCE/Google Kubernetes Engine deploys an ingress controller on the master.

By changing `ingress_nginx_nodeselector` plus custom k8s node
label, user could customize the DaemonSet deployment target.

If `ingress_nginx_nodeselector` is empty, will deploy DaemonSet on
every k8s node.

-   cephfs-provisioner 06fddbe2 (https://github.com/kubernetes-incubator/external-storage/tree/06fddbe2/ceph/cephfs)

Noteable changes from upstream:

-   Added storage class parameters to specify a root path within the backing cephfs and, optionally, use deterministic directory and user names (https://github.com/kubernetes-incubator/external-storage/pull/696)
-   Support capacity (https://github.com/kubernetes-incubator/external-storage/pull/770)
-   Enable metrics server (https://github.com/kubernetes-incubator/external-storage/pull/797)

Other noteable changes:

-   Clean up legacy manifests file naming
-   Remove legacy manifests, namespace and storageclass before upgrade
-   `cephfs_provisioner_monitors` simplified as string
-   Default to new deterministic naming
-   Add `reclaimPolicy` support in StorageClass

With legacy non-deterministic naming style (where $UUID are generated ramdonly):

-   cephfs_provisioner_claim_root: /volumes/kubernetes
-   cephfs_provisioner_deterministic_names: false
-   Generated CephFS volume: /volumes/kubernetes/kubernetes-dynamic-pvc-$UUID
-   Generated CephFS user: kubernetes-dynamic-user-$UUID

With new default deterministic naming style (where $NAMESPACE and $PVC are predictable):

-   cephfs_provisioner_claim_root: /volumes
-   cephfs_provisioner_deterministic_names: true
-   Generated CephFS volume: /volumes/$NAMESPACE/$PVC
-   Generated CephFS user: k8s.$NAMESPACE.$PVC

On Aarch64, the default cgroup driver for docker is systemd
instead of cgroupfs. Should conform kubelet to use systemd
as cgroup driver as well to keep it consistent with docker.

Without this change, below exception will be raised.
/usr/bin/docker-current: Error response from daemon: shim
error: docker-runc not installed on system.

Kubespray should not install any helm charts. This is a task
that a user should do on his/her own through ansible or another
tool. It opens the door to wrapping installation of any helm
chart.

Replaced ansible_ssh_host with ansible_host in sample inventory file as the former is deprecated since Ansible v2.0

Fixed the reference of ansible_user in kubespray-defaults role

References:
 - http://docs.ansible.com/ansible/latest/intro_inventory.html

Kubernetes makes this namespace automatically, so there is
no need for kubespray to manage it.

install using Helm:
- Prometheus Operator
- metrics for k8s cluster including: grafana dashboard, alertmanager, node exporters

base project:
https://github.com/coreos/prometheus-operator

Previous PR, raw ansible without Helm:
https://github.com/kubernetes-incubator/kubespray/pull/2499

Addition of the .creds extension to the credentials files generated by password lookup in order for Ansible not to consider them as inventory files with inventory_ignore_extensions set accordingly (#2446)

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
