Subject: Fix: authenticated registry support for containerized hosts

Currently, openshift-anisble supports authentication to
container registries to pull down openshift container images.
The openshift_verison role uses the docker cli to gather
image information from container registries before authentication
credentials are provided by openshift-ansible.

This commit creates the necessary token to authenticate to
private registries during openshift_version.  The token
is generated by the role 'docker' on all hosts where
docker is installed/configured when oreg_auth_users
is defined.

This commit also adds a read-only mount into the
openshift master and node container services.  This
mount is '/var/lib/origin/.docker:/root/.docker:ro'.
This is because the container images do not currently
read the values in '/var/lib/origin/.docker' as this
may be a bug upstream.

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1316341
