Relaxing replying `KafkaTemplate` in `AbstractKafkaListenerContainerFactory`

[nyilmaz]

Since KafkaTemplate has its own message converter, shouldn't we relax that instance property to wildcard types such as: private KafkaTemplate<?, ?> replyTemplate;.

Otherwise spring-kafka forces users of listener container factory to reply exactly the same semantics as listener ie. <K, V>.

What would you think?

Good point; yes.

As a work-around you can just inject KafkaTemplate with no generics and suppress the warning.
