Description

We currently have a compile-dependency on `connect-json`:

<dependency>
  <groupId>org.apache.kafka</groupId>
  <artifactId>connect-json</artifactId>
  <version>0.10.2.0</version>
  <scope>compile</scope>
  </dependency>

The snippet above is from the generated POM of Kafka Streams as of 0.10.2.0 release.

AFAICT the only reason for that is because the Kafka Streams examples showcase some JSON processing, but that’s it.

First and foremost, we should remove the connect-json dependency, and also figure out a way to set up / structure the examples so we that we can continue showcasing JSON support. Alternatively, we could consider removing the JSON example (but I don't like that, personally).
