> If you try to create a topic and the replication factor cannot be satisfied,
> Kafka will return `INVALID_REPLICATION_FACTOR`. If the topic already exists,
> we should probably return `TOPIC_ALREADY_EXISTS` instead. You won't see this
> problem if using TopicCommand because we check existence prior to creating
> the topic.
