For containerized masters, we previously create a wrapper script to run
the docker CLI image and clean up afterward, but this approach is much
slower than having the binary on the native system.

Instead we now use an ansible module to handle the logic of syncing the
various OpenShift binaries and symlinks for client tools out onto the
host. The module will correctly report changed if modifications were
needed.

Substantial speed improvement for containerized installs which requires
many openshift/oc commands.

Docker 1.10 is no longer tolerant of commands like "docker pull
myimage:" when we do not have an image tag in play.

Adjust all occurrences with one that only includes the : if a version is
defined.

Adjust the containerized CLI wrappers for a similar problem.

Starting to remove openshift.docker.openshift_version fact usage.

openshift_version should no longer contain a leading 'v' for
containerized installs, just a version number.

This is the containerized openshift_pkg_version equivalent.  Originally I was
hoping to reuse openshift_pkg_version for containerized installs but the fact
that it's very coupled to yum made that pretty ugly.

However, I did opt to rely on the previously existing 'openshift_version'
variable.  Containerized and RPM installs can both use that variable and it
will be set appropriately if either openshift_pkg_version or
openshift_image_tag are set.  I suspect someday containerized installs will be
the only option and I didn't can to have thinkgs like openshift_pkg_version and
openshift_image_tag in the playbooks anymore the necessary.

Also remove -a STDIN,STDOUT,STDERR that's the default
