### Purpose This PR adds support for Iceberg partition transforms in the Iceberg sink. Previously, only identity partitioning was supported. With this change, users can utilize standard Iceberg transforms like `year`, `month`, `day`, `hour`, `bucket`, and `truncate` when defining partition keys. ### Changes - **`IcebergDataSinkFactory`**: Updated to parse partition keys containing transforms from the `sink.partition-key` configuration. - **`IcebergMetadataApplier`**: Implemented logic to apply partition transforms when creating new Iceberg tables. - **`IcebergDataSinkOptions`**: Updated documentation to include examples of partition transforms. - **Tests**: Added `IcebergDataSinkFactoryTest` cases to verify that partition specs are correctly generated for various transforms. ### Usage Users can now specify partition keys with transforms in the `sink.partition-key` option. **Example:** ```properties sink.partition-key = "testdb.table1:year(create_time);testdb.table2:bucket[16](id)" -- This is an automated message from the Apache Git Service.
