To configure core plugin or service plugins, instead of using class names,
simpler names can also be used, ex:
service_plugins = router, firewall, lbaas
For compatibility with previous versions, the class name of a plugin can be
specified instead of its entrypoint name, ex:
service_plugins = router, neutron.services.firewall.fwaas_plugin.FirewallPlugin, lbaas
