Fixes #10493 ### Description Implements better support for Avro unions in the Avro extensions. Currently when ingesting data that contains unions unless the union is always the same value it will return mixed type results. This PR addresses the problem by exploding union fields into maps keyed by the union member type or type name in the case of named types (enums, fixed, records). The method was chosen as it's similar to what is done on other systems that support ingesting Avro data, such as Google BigQuery which details their Avro compatibility here: https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-avro#avro_conversions <hr> This PR has: - [ ] been self-reviewed. - [ ] added documentation for new or modified features or behaviors. - [ ] added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader. - [ ] added unit tests or modified existing tests to cover new code paths, ensuring the threshold for [code coverage](https://github.com/apache/druid/blob/master/dev/code-review/code-coverage.md) is met. - [ ] added integration tests. - [ ] been tested in a test Druid cluster. <hr> ##### Key changed/added classes in this PR * `AvroFlattenerMaker` * `GenericAvroJsonProvider` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
