KAFKA-2475: Make Copycat only have a Converter class instead of Serializer,
Deserializer, and Converter.
The Converter class now translates directly between byte[] and Copycat's
data
API instead of requiring an intermediate runtime type like Avro's
GenericRecord
or Jackson's JsonNode.

Reduce copycat configs to only specify a converter or serializer, not both

Key: KAFKA-2475
URL: https://issues.apache.org/jira/browse/KAFKA-2475
Project: Kafka
Issue Type: Sub-task
Components: copycat
Reporter: Ewen Cheslack-Postava
Assignee: Ewen Cheslack-Postava
Fix For: 0.8.3
Ultimately, all we care about is getting from byte[] - Copycat data API. The
current split of the interfaces makes it easy to reuse existing serializers,
but you still have to implement a new class.
It will be simpler, both conceptually and by requiring fewer configs, to
combine both these steps into a single API. This also allows certain formats
to preserve more information across these (e.g. for primitive types in
schema, which otherwise could lose certain schema information).
