23c9071c30 Added file and container image caching (#4828)
* 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.

d6fd0d2aca Enable delegating all downloads (binaries, images, kubeadm images) (#4420)
* 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

64f48bf84c Update ansible.md (#4599)
Ansible 2.0 has deprecated the “ssh” from ansible_ssh_host.

Updating the docs to be more aligned with the Ansible version used in the sample/inventory.ini file as well.
Also adding `[bastion]` group in the docs to avoid confusion.

12c6b5c3eb openSUSE: Use Leap 15.0 instead of 42.3 (#4442)
* Vagrantfile: Bump openSUSE to Leap 15.0

* roles: container-engine: Add 'containerd' package for openSUSE

The 'containerd' package contains the docker-containerd and
docker-containerd-shim binaries. We also need to ensure that the latest
version is installed since an older version may already be present (eg GCE
images)

* Remove docker log-opts for opensuse

* roles: bootstrap-os: Use lowercase 'o' for openSUSE

OpenSUSE is not a valid family name. The correct one is openSUSE

* roles: bootstrap-os: Update zypper cache before first installation

The zypper cache may be outdated so ensure that it's fully updated
before we try and install the bootstrap packages.

5f12b7aedf Remove kubedns and dnsmasq. Move dns_late phase after apps (#4406)
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.

3ce033995f Documented docker_version acceptable values (#3901)
Added a line documenting where to find acceptable values for the
`docker_version` setting. If you use a value that is not used as
a key value by `docker_versioned_pkg` the container-engine/docker
playbook will throw a "Unexpected templating type error". (e.g.
If you use '18.06.1' or '18.06.1-ce', neither of which is used
as a key value of `docker_versioned_pkg`, rather than '18.06',
you'll get an error when installing on Ubuntu 18.04.)

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.

bc9e14a762 Adds support for Multus (multiple interfaces) CNI plugin (#3166)
* Adds support for Multus (multiple interfaces) CNI plugin

Multus is a latin word for "Multi". As the name suggests, it acts as a
Multi plugin in Kubernetes and provides multiple network interface
support in a pod. Multus uses the concept of invoking delegates by
grouping multiple plugins into delegates and invoking them in the
sequential order of the CNI configuration file provided in json format.

* Change CNI version (0.1.0->0.3.1) of Contiv to be compatible with Multus
