kubernetes/master role defines this value as an empty string
when using a cloud provider, not undefined. The check was updated
accordingly.

* Require minimum version of Kubernetes
* Remove checksums for kubernetes version 1.12
* Add kube_version to precheck output and add min required version to README
* Fix merge
* Fix defaults
* Fix typo in precheck
* File and container image downloads are now cached localy, so that repeated vagrant up/down runs do not trigger downloading of those files. This is especially useful on laptops with kubernetes runnig locally on vm's. The total size of the cache, after an ansible run, is currently around 800MB, so bandwidth (=time) savings can be quite significant.
* When download_run_once is false, the default is still not to cache, but setting download_force_cache will still enable caching.
* The local cache location can be set with download_cache_dir and defaults to /tmp/kubernetes_cache
* A local docker instance is no longer required to cache docker images; Images are cached to file. A local docker instance is still required, though, if you wish to download images on localhost.
* Fixed a FIXME, wher the argument was that delegate_to doesn't play nice with omit. That is a correct observation and the fix is to use default(inventory_host) instead of default(omit). See ansible/ansible#26009
* Removed "Register docker images info" task from download_container and set_docker_image_facts because it was faulty and unused.
* Removed redundant when:download.{container,enabled,run_once} conditions from {sync,download}_container.yml
* All features of commit d6fd0d2aca by Timoses <timosesu@gmail.com>, merged May 1st 2019, are included in this patch. Not all code was included verbatim, but each feature of that commit was checked to be working in this patch. One notable change: The actual downloading of the kubeadm images was moved to {download,sync)_container, to enable caching.
Note 1: I considered splitting this patch, but most changes that are not directly related to caching, are a pleasant by-product of implementing the caching code, so splitting would be impractical.
Note 2: I have my doubts about the usefulness of the upload, download and upgrade tags in the download role. Must they remain or can they be removed? If anybody knows, then please speak up.
* Make local volume provisioner dir mode a variable
I need to change this for Nagios monitoring. Others may
need to as well. Had to close previous commits, sorry for
the spam.

Task "kube-roter | Set cni directory permissions"

Task "kube-router | Copy cni plugins"
copies the binaries from the archive setting the ownership
back to "root"

* Add support for arm images for hyperkube, kubeadm and cni_binary
* Add dummy etcd checksum for arm
This commit adds dummy etcd checksum for arm to avoid "no attribute" error
during setup.
* Add etcd host assert check
* Add 1.13.4 checksums of kubeadm and hyperkube for arm
* Update checksums of kubeadm and hyperkube for arm
* Add dummy checksums for calicoctl_binary_checksums dict
* disable gather_facts because it causes tests to fail
* Remove architecture check for etcd, due to unable to run tests
* Added pod psp in Rancher Local Path Provisioner
Added pod security policy (psp) in Rancher Local Path Provisioner.

* Apply psp for Rancher Local Path Provisioner only when local_path_provisioner_namespace is not kube-system and also reorganized the templates
Kubespray waits exit of every drain before run other one.
Running drain every after each other seems better than parallel, because we should check resources availability every time.
But, this way, we have one additional problem: possible restart pods on the nodes that are killed little bit later.
Fast cordon before heavy drain seems like an easy solution.
Error starting nginx because in requiredDropCapabilities is dropped all capabilities.
The nginx requires the following capabilities:
- CHOWN
- SETGID
- SETUID

Without this, pulls are considered for all
hosts groups, even if not targetted by the downloads
`groups` list. Hence, a download/sync is triggered
even though the host does not require the image.
* Disable kube_api_anonymous_auth by default to secure the setup
* Disable metrics-server in addons. Health endpoint is slow and unstable
* Fix anonymous-auth missing in configuration
* Cleanup a bit
* Fix kube anon auth
* Download to delegate and sync files when download_run_once
* Fail on error after saving container image
* Do not set changed status when downloaded container was up to date
* Only sync containers when they are actually required
Previously, non-required images (pull_required=false as
image existed on target host) were synced to the target
hosts. This failed as the image was not downloaded to
the download_delegate and hence was not available for
syncing.
* Sync containers when only missing on some hosts
* Consider images with multiple repo tags
* Enable kubeadm images pull/syncing with download_delegate
* Use kubeadm images list to pull/sync
'kubeadm config images pull' is replaced by collecting the images
list with 'kubeadm config images list' and using the commonly
used method of pull/syncing the images.
* Ensure containers are downloaded and synced for all hosts
* Fix download/syncing when download_delegate is a kubernetes host
When docker_container_storage_setup is false,
docker service should not depend on docker-storage-setup service,
because it's not installed.
For example, when using overlay2 on recent RHEL 7/Centos 7 kernels,
you most likely don't need it.
* Fix nodeselectors for contiv and nginx-ingress

add the support of the folling property in azure-credential-check.yml
- azure_loadbalancer_sku: Sku of Load Balancer and Public IP. Candidate values are: basic and standard.
- azure_exclude_master_from_standard_lb: excludes master nodes from standard load balancer.
- azure_disable_outbound_snat: disables the outbound SNAT for public load balancer rules
- useInstanceMetadata: Use instance metadata service where possible
- azure_primary_availability_set: (Optional) The name of the availability set that should be used as the load balancer backend
We don't need to support upgrades from 2 year old installs,
just from the last major version.
Also changed most retried tasks to 1s delay instead of longer.
* Add README to bootstrap-os role
* Rework bootstrap-os once more
* Document workarounds for bugs/deficiencies in Ansible modules

* Remove installation of additional packages and repositories
* Merge Ubuntu and Debian tasks
* Remove pipelining setting from default playbooks
* Fix OpenSUSE not running its required tasks
The docker service provided by the containers-basic bundle is masked
in ClearLinux distribution. This is causing errors in the following
steps. This commit ensures that the unit is not masked.
* Use K8s 1.14 and add kubeadm experimental control plane mode
This reverts commit d39c273d96.
* Cleanup kubeadm setup run on first master
* pin kubeadm_certificate_key in test
* Remove kubelet autolabel of kube-node, add symlink for pki dir
