This is where naming gets tricky :)  I would tend to think of LBaaS a
service as an independently loadable component within Quantum, which is to
say, your choice of a LBaaS back-end would be completely independent of
your choice of a "core" Quantum plugin.  As a result, a provider could
choose to expose only the load-balancer API to tenants, if that is what
that operator wanted.  I'm not sure if this is the same as what you
suggest.  Either way, I think the right thing here is to focus on what
different deployment scenarios we see this being used in, then we can
figure out how tightly coupled it should be to the man quantum service.
