Thanks all for the information. Now I got it. Maybe the issue's title is not
clear. Now I change the title from `Support to read iceberg table's metadata
with Flink` to `Support icberge table's metadata column`.
What I mean is that we can implemet `SupportsReadingMetadata` for
`IcebergTableSource` just like `SparkTable` implements
`SupportsMetadataColumns`. So that user can use such Flink SQL to know which
file the row comes from by the column `file_path`.
```
CREATE TABLE icberg_t(
id STRING,
file_path STRING METADATA
) with
('connector' = 'iceberge', xxx);
SELECT id, file_path FROM icberg_t;
```
