Adding backwards compatible test with
3.0.0and3.1.0version by serializing objects on lower versions and deserializing them on snapshot version.SchemaManagertest runs on3.1.0only since commit bcad5d9 and [FLINK-34653] Support table merging with route #3129 changesSchemaRegistryserialization fields and breaks backwards compatibility.SchemaRegistrytest runs on3.1.0only, since it storesSchemaManagerin its state.ChangeTableInfotest runs on3.1.0only since Transform feature does not exist in3.0.x.Also noticed that there's no much classes using versioned serialization protocol, which couldn't guarantee backwards compatibility. Needs more discussion on how to refactor them.
