splitter: 1.0.0-spring-ingetration - message-driven channel-adapter

* Instead of the `@InboundChannelAdapter`-annotation, a
  `KafkaMessageDrivenChannelAdapter` can be instanciated.
* The adapter takes a `AbstractMessageListenerContainer` as constructor
  argument.
* The output-channel must be set explicitly on the created instance.
* This approach is advantageous, if technical details are important,
  because the used `MessageListenerContainer` can be configured explicitly.
