IMPALA-11776: Use hive.metastore.table.owner for create iceberg table
IMPALA-11429 made the creation of an Iceberg table happen in 2 steps.
The first step creates the table, however, with wrong owner and the
second step is an ALTER TABLE to set the correct table owner.
Since Iceberg 1.1.0 there is now a way to provide a table owner via a
table property so we can make the create table operation to take one
step again.
https://github.com/apache/iceberg/pull/5763
https://github.com/apache/iceberg/pull/6154
This patch implements this behavior, when creating an Iceberg table
through HiveCatalog, specifying HMS_TABLE_OWNER as
hive.metastore.table.owner in properties can do it in one step.
Testing:
- Use the existing test test_iceberg.py test_table_owner.

> The owner should be the user executing the query.
> Unfortunately Iceberg doesn't allow us setting the owner of the table. It
> uses the system-wide property "user.name" to set the owner:

> We might need Iceberg-side modifications as well to specify the owner.
> Alternatively we could add an exter alter_table() RPC to change the owner.
