Remove LBaaS support from devstack
Devstack support for LBaaS is being migrated to an external
plugin in the neutron-lbaas repository. The only LBaaS-
specific code that remains in devstack is a hook to support
existing configs that enable q-lbaas. In that case, load
the external plugin if necessary.
