Review comment:
From my understanding, I think we can only consider FINISHED due to that
when transit to CANCELED and FAILED , all execution vertices will be canceled
and the thus the result partition will be canceled via
`sendReleaseIntermediateResultPartitionsRpcCall`.
However, with region failover, an execution may need to re-run after it
turns into FINISHED. This happens for cases like `A -> C, B->C`, A and B are
all finished but C fails to read data from A, then B also need to re-execute if
the partition is random (like RebalancePartition). When the execution vertex is
`resetForNewExecution`, the result partition of previous execution is not
released. Then when we `cancel` or `failGlobal` on the ExecutionGraph, it will
also only consider the last execution, then the result partitions of the
previous executions may not get released explicitly.
