Change subject: IMPALA-14638: Schedule union of iceberg metadata scanner to

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 new planner and runtime tests for this case.
