Review comment:
sorry for the late, I prefer not to do this. Since
`RepartitionOperation` can affect the behavior of AQE, the semantics of
`RepartitionOperation` have a little different from previous.
Currently, the `RepartitionOperation` behavior with AQE framwork follows:
* `Repartition` does not use AQE
* `RepartitionByExpression` use AQE depends on `optNumPartitions`
* `RebalancePartitions`(if extend) always use AQE
And the rule `CollapseRepartition` may not effective in all use case.
