Example code illustrating usage

The README is a good first step at docs, but its been suggested that there be code examples illustrating the usage of this library.

Also, if it would be great if we can see the consumer in action. My consumer works fine with ExecutorService (single thread model) but healthcheck fails as the consumer is not thread safe

@saurav-2104 good to know, I had run into similar problems with a previous consumer health check approach that caused me to implement CheckableConsumer. I’ll see if I can repro

I followed the README for implementing Kafka Consumer in my code but looks like KafkaConsumerBundle does not have an empty constructor.
It will be great if more examples are provided for using Kafka in dropwizard.
