Kafka allows to configure default user quotas which apply to all users who do not have a specific quota setting. But they can be configured only dynamically using the Kafka Admin APi / kafka-config.sh. It might be useful to be able to configure them declaratively in the Kafka CR.

Open points:

• Should we also allow declarative configuration of the default client quota? We currently don't support declarative management of client quotas at all. So probably not
