### What changes were proposed in this pull request?
Some Hive column datatypes are currently not supported by Iceberg. In case
of CTAS statements and materialized views Hive converts some of the source
table column types to a compatible Iceberg column type.
For the conversion a select operator is generated. The number of input and
output columns has to be the same. The number of output columns also depends on
dynamic partitioning but in case of Iceberg target table partitioning is
handled by the storage handler so it should be ignored.
### Why are the changes needed?
To support partitioned materialized view stored by iceberg and to support
ctas statements which create tables stored by Iceberg but the source
table/query has a column datatype which is not supported by Iceberg.
### Does this PR introduce _any_ user-facing change?
No. But such statements runs successfuly.
### How was this patch tested?
```
mvn test -Dtest.output.overwrite -Dtest=TestIcebergCliDriver
-Dqfile=ctas_iceberg_orc.q,mv_iceberg_partitioned_orc.q,mv_iceberg_partitioned_orc2.q
-pl itests/qtest-iceberg -Piceberg -Pitests
