Change subject: IMPALA-11908: Parser change for Iceberg metadata querying ...................................................................... IMPALA-11908: Parser change for Iceberg metadata querying This change extends parsing table references with Iceberg metadata tables. The TableName class has been extended with an extra vTbl field which is filled when a virtual table reference is suspected. This additional field helps to keep the real table in the statement table cache next to the virtual table, which should be loaded so Iceberg metadata tables can be created. Iceberg provides a rich API to query metadata, these Iceberg API tables are accessible through the MetadataTableUtils class. Using these table schemas it is possible to create an Impala table that can be queried later on. Querying a metadata table at this point is expected to throw a NotImplementedException. Testing: - Added E2E test to test it for some tables.
