The RPM file that's provided by upstream can be used for SUSE
distributions as well. Moreover we simplify the playbook to use
the 'package' module to install packages across different distros.

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.
Depending on the VM configuration, vagrant may either use 'rsync' or
vboxfs for populating the working directory to the VM. However, vboxfs
means that any files created by the VM will also be present on the host.
As such, lets be explicit and always use 'rsync' to copy the directory
to the VM so we can keep the host copy clean. Moreover, the default
rsync options include '--copy-links' and this breaks rsync if there are
missing symlinks in the working directory like the following one:
Error: symlink has no referent:
"/home/user/kubespray/contrib/network-storage/glusterfs/group_vars"
As such, we override the default options to drop --copy-links.
