IMPALA-11672: Update 'transient_lastDdlTime' for Iceberg tables
'transient_lastDdlTime' table property was not updated for Iceberg
tables before this change. Now it is updated after DDL operations
including DROP PARTITION as well.
Renaming an Iceberg table is an exception:
Iceberg does not keep track of the table name in the metadata files,
so there is no Iceberg transaction to change it.
The table name is a concept that exists only in the catalog.
If we rename the table, we only edit our catalog entry, but the metadata
stored on the file system - the table's state - does not change.
Therefore renaming an Iceberg table does not change the
'transient_lastDdlTime' table property because rename is a
catalog-level operation for Iceberg tables, and not table-level.
Testing:
- added managed and non-managed Iceberg table DDL tests to
test_last_ddl_update.py
