Make glusterfs the default sc when deploying with CNS

GlusterFS is the recommended storage solution for OpenShift. Mark the
deployed GlusterFS cluster as the default storage class when deploying
with CNS.

This is possible to change it back to not being the default storage
class by setting 'openshift_storage_glusterfs_storageclass_default:
false' in the OpenShiftGlusterNodeVars heat parameter.
