Implemented the stop-gap solution of declining checkpoints if an operator is partially finished and contain UnionListState in 3ccd984dedd1d5b6fef14c5217c6830a49bd1ecc..2f5655a085adcb7723ccf8045f29cae340e33e81

> Most legacy source operators would record the offset for each partitions, and after recovery it would read from the recorded offset. If before a checkpoint some subtasks are finished, the corresponding partition offsets would be deserted in the checkpoint. Then if the job recover with this checkpoint, the legacy source would re-discovery all the partitions and for those finished tasks, the legacy source would re-read them since their offsets are not recorded.
> Therefore, we would like to fail the checkpoint if some legacy source operators have part of subtasks finished.
