Fix deployment of gluster with openshift AllInOne
Fix deployment of gluster with openshift AllInOne

When TripleO deploys openshift with CNS, it configures it to setup
gluster for both the worker nodes and the image registry. However, the
code was incorrectly adding the glusterfs_registry group only for the
Infra node and was forgetting about the AllInOne role.
