Subject: [PATCH] Clone neutron_lbaas for midonet plugin

MidoNet plugin needs the 'neutron_lbaas' module available when it
starts up without needing to start the LBaaS service.  After the
advanced service split, however, devstack clones 'neutron_lbaas'
only when the 'lbaas' service is enabled.  To get around this
conflict, clone 'neutron_lbaas' everytime midonet is configured
as the Neutron plugin.
