Description

Currently, only the org.apache.flink.formats.json.JsonRowFormatFactory is able to use the information provided by the table schema to derive the JSON format schema. Avro should support this as well in order to avoid specifying a schema twice. This requires the inverse operation that org.apache.flink.formats.avro.typeutils.AvroSchemaConverter does. Instead of avroschema-to-typeinfo we need a typeinfo-to-avroschema converter.
