Bug Description

Neutron routed networks was enabled by default[1], with the switch
to OVN it was removed[2] from the list of default service plug-ins.

It makes sense to enable the plug-in by default so that it's easy
to scale out existing provider networks without being limited by
the restrictions[3] related to scaling existing provider networks
that was created prior to enabling the service_plugin.
