Schema Registry Plugin Versions Save

This realease is a big one with a lot of features :sparkles: :

• Update support for Avro schemas
• Add support for Json schemas
• Add support for Protobuf schemas There is a new DSL (breaking change for Avro) to reference dependencies between schemas, they no longer need to be defined in the same project for the registration/compatibility.

On the technical side :wrench: :

• Kotlin 1.4 usage (no feature used yet)
• Use Testcontainer and Junit5 parameterized in Integration tests
• Full example using a gradle multi module project and avast docker-compose plugin

Thank you @clatko-globe for the help and the contribution ! :pray:
