Change subject: IMPALA-14638: Schedule union of iceberg metadata scanner to coordinator ...................................................................... IMPALA-14638: Schedule union of iceberg metadata scanner to coordinator On clusters with dedicated coordinators and executors the Iceberg metadata scanner fragment(s) must be scheduled to coordinators. IMPALA-12809 ensured this for most plans, but if the Iceberg metadata scanner is part of a union of unpartitioned fragments a new fragment is created for the union that subsumes existing fragments and loses the coordinatorOnly flag. Fixes cases where a multi-fragment plan includes a union of iceberg metadata scans by setting coordinatorOnly on the new union fragment. Adds a new test for this case.
