* Fix the jinja expression for openstack_tenant_id
OS_PROJECT_ID is obsolete in keystone v3 and jinja expression
doesn't set openstack_tenant_id as expected because of
undefined env var. Fixed the expression.

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.
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.

The number of pods on a given node is determined by the --max-pods=k
directive. When the address space is exhausted, no more pods can be
scheduled even if from the --max-pods-perspective, the node still has
capacity.
The special case that a pod is scheduled and uses the node IP in the
host network namespace is too "soft" to derive a guarantee.
Comparing kubelet_max_pods with kube_network_node_prefix when given
allows to assert that pod limits match the CIDR address space.
While `do` looks cleaner, forcing this extra option in ansible.cfg
seems to be more invasive. It would be better to keep the traditional
approach of `set dummy = ` instead.
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

kube-proxy is complaining of missing modules at startup. There is a plan
to also support an LVS implementation of kube-proxy in additon to
userspace and iptables
* Add Contiv support
Contiv is a network plugin for Kubernetes and Docker. It supports
vlan/vxlan/BGP/Cisco ACI technologies. It support firewall policies,
multiple networks and bridging pods onto physical networks.
* Update contiv version to 1.1.4
Update contiv version to 1.1.4 and added SVC_SUBNET in contiv-config.
* Load openvswitch module to workaround on CentOS7.4
* Set contiv cni version to 0.1.0
Correct contiv CNI version to 0.1.0.
* Use kube_apiserver_endpoint for K8S_API_SERVER
Use kube_apiserver_endpoint as K8S_API_SERVER to make contiv talks
to a available endpoint no matter if there's a loadbalancer or not.
* Make contiv use its own etcd
Before this commit, contiv is using a etcd proxy mode to k8s etcd,
this work fine when the etcd hosts are co-located with contiv etcd
proxy, however the k8s peering certs are only in etcd group, as a
result the etcd-proxy is not able to peering with the k8s etcd on
etcd group, plus the netplugin is always trying to find the etcd
endpoint on localhost, this will cause problem for all netplugins
not runnign on etcd group nodes.
This commit make contiv uses its own etcd, separate from k8s one.
on kube-master nodes (where net-master runs), it will run as leader
mode and on all rest nodes it will run as proxy mode.
* Use cp instead of rsync to copy cni binaries
Since rsync has been removed from hyperkube, this commit changes it
to use cp instead.
* Make contiv-etcd able to run on master nodes
* Add rbac_enabled flag for contiv pods
* Add contiv into CNI network plugin lists
* migrate contiv test to tests/files
Signed-off-by: Cristian Staretu <cristian.staretu@gmail.com>
* Add required rules for contiv netplugin
* Better handling json return of fwdMode
* Make contiv etcd port configurable
* Use default var instead of templating
* roles/download/defaults/main.yml: use contiv 1.1.7

Some time ago I think the hardcoded `/var/lib/docker` was required, but kubelet running in a container has been aware of the Docker path since at least as far back as k8s 1.6.
Without this change, you see a large number of errors in the kubelet logs if you installed with a non-default `docker_daemon_graph`
