The containerd service and socket files have been dropped from the
openSUSE docker package so we should not require them in the docker
service anymore. This makes the docker service file look similar to
the one shipped by the openSUSE package.

Add support install python-pip from local yum repository if local yum repository exist.

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.)
