Support NFS backend for Glance (via Pacemaker)
Adds support for NFS backend in Glance by allowing the storage directory for the 'file' backend to be a mount managed by Pacemaker. Default behavior is unchanged. Since the Pacemaker-related parameters are not exposed on top level, change storage-environment.yaml to use parameter_defaults instead of parameters. Depends on a Heat fix for environment file's parameter_defaults to work well with JSONs and comma delimited lists (see Depends-On).
