Reactor Kafka examples

[almogtavor]

It would be great if Kafka samples would be added. This is a pretty common use case that doesn't have lots of examples. Especially when combined with libraries like Spring Data.

Great idea, I have created a task for myself #261, I will create an example to demonstrate Reactor Kafka/Spring WebFlux ASAP.

Actually I think it would be better if the example would be more of a data pipeline kind. The Webflux usage with Kafka is pretty obvious into my opinion. I suggest an application that consumes a Kafka topic, creates batches, and writes them reactively to Mongo for example.
