ProducerMessage

ProducerMessage represents zero or more ProducerRecords, together with an arbitrary passthrough value, all of which can be used with KafkaProducer. ProducerMessages can be created using one of the following options.

- ProducerMessage#single to produce exactly one record and then emit a ProducerResult with the result and specified passthrough value.
- ProducerMessage#multiple to produce zero or more records and then emit a ProducerResult with the results and specified passthrough value.
- ProducerMessage#passthrough to produce exactly zero records, only emitting a ProducerResult with the specified passthrough value.

The passthrough and records can be retrieved from an existing ProducerMessage instance.

For a ProducerMessage to be usable by KafkaProducer, it needs a Traverse instance. This requirement is captured in ProducerMessage via traverse.
