* use dpkg_selections module to hold docker-ce on Debian family hosts

* removed debian_docker.j2 template as it is no longer required

* 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The zypper cache may be outdated so ensure that it's fully updated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.

Omit does not work in the context of yum_repository proxy. The ansible documentation specifies to use _none_ to disable the global proxy setting. (#4225)

Fixing an issue where trying to install docker-ce-18.09 on rhel7 nodes (or potentially centos 7) without an enabled extras repo the installation will fail because container-selinux >= 2.9 is required. The check for container-selinux upfront should obviate the need for adding an extras repo if the node is able to find it from another source. (#4161)

This reverts commit 51f4e658.

If the 'docker' package is already installed, then the handlers will not
run and the service will not be (re-)started. As such, lets make sure
that the service is started even if the packages are already installed.

Add support for installing Docker on SUSE distributions. The Docker
repository at https://yum.dockerproject.org/repo/main/ does not support
recent openSUSE distributions so the only alternative is to use the
packages from the distro repositories. This however renders the
'docker_version' Ansible variable useless on SUSE.

* Remove old docker packages

This removes docker packages that are obsolete if docker-ce packages are to be installed, which fixes some package conflict issues that can occur during upgrades.

* Add support for setting obsoletes=0 when installing docker with yum

Support docker-ce and docker-engine include redhat/centos ubuntu debian

import_tasks will consume far less memory, so it should be
used whenever it is compatible.

Renaming runtime docker_version to prevent setting that
value on the command line from breaking the play run.

This fixes #2081

This allows overriding of apt repo endpoints when internet sources are not accessible. Additionally, switch to using the dockerproject.org gpg key url for apt instead of keyservers.net

* Set no_proxy to all local ips

* Use proxy settings on all necessary tasks

* Adding yaml linter to ci check

* Minor linting fixes from yamllint

* Changing CI to install python pkgs from requirements.txt

- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements

Updates based on feedback

Simplify checks for file exists

remove invalid char

Review feedback. Use regular systemd file.

Add template for docker systemd atomic

Using the command module instead of raw.
Also fixed the syntax.

Docker upgrade doesn't auto-restart docker, causing failures
when trying to start another container

Also update reset.yml to do more dns/network related cleanup.
