Review Comment:
This is a request-side flag, not a result field.
The result already carries the actual routing value through
TOlapTablePartition.load_tablet_idx. FE needs this request flag to know
whether
the caller sink is running in load_to_single_tablet/FIND_TABLET_EVERY_SINK
mode
when it creates or replaces runtime auto partitions.
Without this flag, createPartition()/replacePartition() only know the table
and
partition metadata, but not the original sink routing mode. Then FE cannot
decide
whether it should assign/cache load_tablet_idx for the newly created/replaced
random partition.
