Fair enough ... though I think (a) would also have that quality
of encapsulation, as long as the new integrated-gate-ceilometer
project-template was only referenced by the openstack/ceilometer

I'm not sure it makes a great deal of difference though, so would
be happy enough to go with either (b) or (a).

Fair point.
