Tutorial on how to serialize protocolbuffers and avro

[krickert]

Feature description

https://github.com/krickert/micronaut-kafka-container-test-example

I created a micronaut example with 3 different serialization modules:

• String message
• Apache Avro Message
• Google protocol buffers message

I found there wasn't a single good place to get this going easily in micronaut. So while I was testing as I converted my project from avro to protocol buffers, I wrote these three examples.

If you find it useful, I'd be glad to include it and expand it as a guide for micronaut users.

Also, the current instructions mention the kafka embedded server but that's no longer the case. This code can be used as an example on how to test kafka via a container as well.

Thoughts?
