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.
* feat(external-provisioner/local-path-provisioner): adds support for local path provisioner
Helpful for local development but also in production workloads (once the
permission model is worked out) where you have redundancy built into the
software uses the PVCs (e.g. database cluster with synchronous
replication)

* fix(local-path-provisioner): moves image repo/tag to download role
* test(gce_centos7-flannel): enables local-path-provisioner in test case
* fix(addons): add image repo/tag to commented default values
* fix(local-path-provisioner): typo in jinja template for local path provisioner
* style(local-path-provisioner): debug flag condition re-formatted
* fix(local-path-provisioner): adds missing default value for debug flag
* fix(local-path-provisioner): syntax fix for debug if condition end
* fix(local-path-provisioner): jinja template syntax: if condition white space
Currently, the task `container_download | download images for kubeadm config images` fetches etcd image even though it's not required (etcd is bootstrapped by kubespray, not kubeadm).
`kubeadm-images.yaml` is only a subset of `kubeadm-config.yaml`, therefore ``kubeadm config images pull` will try to get all this list (including etcd)
```
# kubeadm config images list --config /etc/kubernetes/kubeadm-images.yaml
k8s.gcr.io/kube-apiserver:v1.13.2
k8s.gcr.io/kube-controller-manager:v1.13.2
k8s.gcr.io/kube-scheduler:v1.13.2
k8s.gcr.io/kube-proxy:v1.13.2
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd:3.2.24
k8s.gcr.io/coredns:1.2.6
```
When using the `kubeadm-config.yaml` though, it doesn't list etcd image:
```
# kubeadm config images list --config /etc/kubernetes/kubeadm-config.yaml
k8s.gcr.io/kube-apiserver:v1.13.2
k8s.gcr.io/kube-controller-manager:v1.13.2
k8s.gcr.io/kube-scheduler:v1.13.2
k8s.gcr.io/kube-proxy:v1.13.2
k8s.gcr.io/pause:3.1
k8s.gcr.io/coredns:1.2.6
```
This change just adds the etcd endpoints in the `kubeadm-images.yaml` to give a hint to kubeadm it doesn't need etcd image for its boostrapping as etcd is "external".
I confess it is a ugly hack, a better way would be to use a single `kubeadm-config.yaml` for both tasks, but they are triggered by different roles (`kubeadm-images.yaml` is used by download, `kubeadm-config.yaml` by kubernetes/master) at different steps and I didn't want to refactor too many things to prevent breakage.
This is specially useful for offline installation where a whitelist of container images is mirrored on a local private container registry. `k8s.gcr.io/etcd` and `quay.io/coreos/etcd` are two different repositories hosting the same images but using *different tags*!
* coreos/etcd:v3.2.24
* k8s.gcr.io/etcd:3.2.24 (note the missing 'v' in the tag name)
Addressing the discussion started in #4064, this PR moves kubeadm and
hyperkube binaries to /usr/local/bin before running them on the master
nodes.
It is to address the case where local_release_dir points to /tmp
(kubespray default) and /tmp is mounted with noexec mode, preventing
any binaries to be run in that partition.
In role "node", we still move kubeadm to bin_dir only on the worker
nodes.
* Add support for running a nodelocal dns cache
After encountering dns issues in a cluster I was recently working on I
noticed Kubernetes 1.13 introduced support for running a nodelocal dns
cache.
I believe this can usefull for more people.

When `ansible_user` is not root, using `-b` option.
And with `download_run_once` and `download_localhost` set `true`.
Ansible will executes `container_download | upload container images to nodes` task.
It uses rsync to upload images to `/tmp/release/container/`, but the
`container` directory owned by `root`.
