Description

After https://issues.apache.org/jira/browse/FLINK-24617 the partition key handling logic is encapsuled within FileInfoExtractorBulkFormat. We should cleanup this logic from orc and parquet formats, in order to simplify it. Note: Hive still depends on this logic, but it should rather use FileInfoExtractorBulkFormat or similar.
