Add support for AVRO

[WesWWagner]

Regarding adding support for Avro... typically most clients are written in a manner that expects the developer to interact with the avro and protobuf libraries directly for their serdes activity.

Can you expand on whether this is a suggestion to automate and abstract this behavior by intervening in consume and produce requests to automatically interface w/ schema and serdes activity ? This would be a break from the norms and standards of how most kafka clients work, but is something I have considered particularly useful if a good pattern were adopted to automate this and not force users of the client to manually code serdes activity.

Yes this is true, we will keep format agnostic, the users of the library will work with Avro or whichever format they choose.
