The DEFAULT/ovs_integration_bridge parameter was deprecated in neutron
in favor of the new ovs/integration_bridge[1] parameter, so
puppet-neutron should use the new parameter accordingly.
Also, that parameter is also available in l3 agent configuration, so
the new parameter, ovs_integration_bridge, was added to l3 agent
manifest.
