## Description This PR adds support for type conversion from avro complex types (MAP, ARRAY, RECORD, UNION) to Pinot JSON column. Currently, only avro type STRING conversion to JSON column is supported. Ingestion of complex types into JSON column can also be done using Ingestion Transform Function; however, this creates issues for us as the Pinot column name can't be of the same name as the input avro field name.) The main changes, that allows for ingesting complex types into JSON, is in `DataTypeTransformer.java` and `AvroSchemaUtil.java`. `PinotDataType.java` contains a bug fix (the fact that a simple string is also a valid json string) which allows for proper conversion of STRING field to JSON column. `AvroIngestionSchemaValidator` was modified to make sure that we no longer reject avro complex type (MAP, ARRAY, RECORD, UNION) field if they are being ingested into JSON column. The rest of the files (`PinotDataTypeTest.java`, `JsonIngestionFromAvroQueriesTest.java`, `AvroRecordExtractorTest.java`, and `AbstractRecordExtractorTest.java`) contain test cases to validate ingestion of avro complex types into JSON column. ## Upgrade Notes Does this PR prevent a zero down-time upgrade?
