[FLINK-5229] [tm] Discard completed checkpoints if a subsequent operator's
checkpoint fails
In case of a failure of any StreamOperator#snapshotState method, all up to
this point created
StreamTaskStates will be discarded. This ensures that a failing checkpoint
operation of a chained
operator won't leave orphaned checkpoint data behind.
