You haven't missed anything - the kafka driver doesn't provide a means
to set a default retry via its configuration.
The expectation is that the caller (nova/neutron) would provide a
retry value when constructing a Notifier instance.

There was such a config option for the rabbitmq driver
(rabbit_max_retries) but that was removed because it broke
*something* - can't remember exactly the reason tho, sorry.
