functional composition using kafka data streams binder does not seem to work

[nmorado]

Use this sample code here functional composition example and instead of using stream-binder-kafka use stream-binder-kafka-streams.

The composition on uppercase|echo does not seem to work.

@nmorado That uppercase|echo should work as that is based on regular Kafka binder (spring-cloud-stream-binder-kafka). Kafka Streams binder does not allow function composition at the moment and in the next version of the binder we are trying to add that feature on experimental basis.

@sobychacko confirmed that it worked for Kafka binder. thanks for the clarification on the plan of adding function composition to Kafka Streams. thanks
