Keystone v3 domain scoped authentication fails

[Senthilnathan Murugappan]

If keystone v3 is enabled we always try to do project scoped authentication.
_user_domain_name is by default set to 'Default' hence the below condtn is always True

https://github.com/Juniper/contrail-controller/blob/R3.2/src/config/vnc_openstack/vnc_openstack/__init__.py#L317
                if self._user_domain_name:
                    kwargs.update({
                        'project_domain_name': self._project_domain_name,
                        'project_name': self._project_name,
                    })
                else:
                    kwargs.update({
                        'domain_id': self._domain_id,
                    })

The condtn should be based on Domain name and not user_domain_name since user_domain_name is reqd for both domain scoped and project scoped auth.

BTW, our current provisioning(SM and Fab) doesnt set admin_project_domain_name and admin_project_name in keystone.conf hence the project scoped auth fails. One may set these manually in keystone.conf till this issue is resolved.
