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).
