IMPALA-12584: Add backend config to restrict data file locations for Iceberg
tables
This change adds backend flag 'iceberg_restrict_data_file_location',
when the flag is set to 'true', Impala will raise an error when at least
one data file of an Iceberg table is outside of the table directory.
The default value of the flag is 'false'.
Tests:
- custom-cluster test added to validate both states of the flag

> Assignee: Peter Rozsa
> Priority: Major
> Labels: impala-iceberg
>
> Similarly to [https://github.com/apache/hive/pull/4910,] Impala should have a
> backend flag to restrict the data file locations of Iceberg tables.
> If the flag is true, Impala should raise an error for Iceberg tables that
> have data files outside of the table directory.
> We should not limit the location of metadata files, so they could be placed
> to a different storage system (e.g. Amazon S3 Express).
> We must also ensure that users cannot create Iceberg tables at arbitrary
> locations.
