Add deliverables info

neutron-vpnaas-dashboard is now not a TC-governed project,
so we don't have an entry in openstack/releases, but deliverable files
in openstack/releases are useful for tracking releases and
we can leverage release tools like 'new-release' from the releases repo.

This commit adds deliverable files to the repo.
