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
