Fix neutron with extensions job

* Extend neutron-with-extensions job with a proper required_projects
  section. It allows to launch all neutron extensions which we have
  in legacy job (except openstack/neutron-fwaas which has
  broken/uncompatible devstack plugin)
* Move load-balancing checks to the separate job
