Change subject: IMPALA-12611: Add support to MAP type Iceberg Metadata table columns ...................................................................... IMPALA-12611: Add support to MAP type Iceberg Metadata table columns This change adds support for querying MAP types from Iceberg Metadata tables. The 'IcebergMetadataScanner.ArrayScanner' java class is renamed to 'CollectionScanner' and extended to be able to handle maps. For arrays the iteration returns the element as before, for maps it returns 'Map.Entry' objects. Note that collections in the FROM clause are still not supported. Testing: - Added E2E tests in iceberg-metadata-tables.test.
