This is a proof of concept for implementing Avro reference using Avro python library.
I used the following PR (implementation using unions) as the base: #926

What works:

  • Direct reference (schema1 --> schema2)
  • Recursive reference (schema1 --> schema1)

What does not work:

  • Indirect references (schema1 --> schema2 --> schema3) - maybe not needed, not sure Schema Registry supports this
  • ... probably other things as well

Instead of using avro unions, use avro lib (function `make_avsc_object()`) to
merge together reference schemas and main schema.
This is just a proof of concept, it does not support indirect references
for example (schema1 --> schema2 --> schema3).

Commented out indirect refs since they don't work, so that other tests can be executed

Maybe we don't need to support indirect refs, it's unclear if Schema Registry supports them
