We have batch size and linger in the [`TopicProducerConfigBuilder`](https://docs.rs/fluvio/0.12.6/fluvio/struct.TopicProducerConfigBuilder.html) We already use [`.topic_producer_with_config()`](https://docs.rs/fluvio/0.12.6/fluvio/struct.Fluvio.html#method.topic_producer_with_config) to build a producer in the CLI, so we can easily add in batch size and linger.
