OVNL3RouterPlugin inherits from L3_NAT_dbonly_mixin, which inherits
from neutron.extensions.l3.RouterPluginBase
As maintenance task expects OVNL3RouterPlugin to behave as
RouterPluginBase, the add_router_interface should have the signature:
add_router_interface(self, context, router_id, interface_info)
Note: With this change, the default behavior of OVNL3RouterPlugin's
_add_neutron_router_interface becomes idem-potent: multiple calls to add
the same interface will not fail. Because of that, the unit test
test_router_add_interface_dup_port no longer makes sense and is being
removed.
