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

Change "command" to "shell" in order for the pipe to work correctly

* Use docker-ce 17.03.2
* Docker-engine may be discarded

Fix can not be used devicemapper driver

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

The search line in /etc/resolv.conf could have
multiple spaces or tabs between domains.
split(' ') will give wrong results in some case,
use split() without argument instead.

e.g.
>>> 'domain.tld	cluster.tld '.split(' ')
['domain.tld\tcluster.tld', '']
>>> 'domain.tld cluster.tld '.split()
['domain.tld', 'cluster.tld']

just a small spelling mistake

Update default docker version to 17.03.1

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

* don't try to install this rpm on fedora atomic

* add docker 1.13.1 for fedora

* built-in docker unit file is sufficient, as tested on both fedora and centos atomic

* Rename dns_server to dnsmasq_dns_server so that it includes role prefix
as the var name is generic and conflicts when integrating with existing ansible automation.
*  Enable selinux state to be configurable with new var preinstall_selinux_state

* Set no_proxy to all local ips

* Use proxy settings on all necessary tasks

* feature: install project atomic CSS on RedHat family

* missing patch for this feature

* sub-role refactor

* Yamllint fix

* Updates Controller Manager/Kubelet with Flannel's required configuration for CNI
* Removes old Flannel installation
* Install CNI enabled Flannel DaemonSet/ConfigMap/CNI bins and config (with portmap plugin) on host
* Uses RBAC if enabled
* Fixed an issue that could occur if br_netfilter is not a module and net.bridge.bridge-nf-call-iptables sysctl was not set

* 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

* Make yum repos used for installing docker rpms configurable
* TasksMax is only supported in systemd version >= 226
* Change to systemd file should restart docker

The docker-network environment file masks the new values
put into /etc/systemd/system/docker.service.d/flannel-options.conf
to renumber the docker0 to work correctly with flannel.

docker-ce is not the .deb package until the repositories are switched over to new "downloads" docker webserver

- Only have ubuntu to test on
  - fedora and redhat are placeholders/guesses
  - the "old" package repositories seem to have the "new" CE version which is `1.13.1` based
- `docker-ce` looks like it is named as a backported `docker-engine` package in some
  places

- Did not change the `defaults` version anywhere, so should work as before
- Did not point to new package repositories, as existing ones have the new packages.

The default version of Docker was switched to 1.13 in #1059.  This
change also bumped ubuntu from installing docker-engine 1.13.0 to
1.13.1.  This PR updates os families which had 1.13 defined, but
were using 1.13.0.

The impetus for this change is an issue running tiller 1.2.3 on
docker 1.13.0.  See discussion [1][2].
