Review comment:
I agree with @pnowojski that `acknowledgeAllCoordinators` is called very
early, and as far as I can see, `acknowledgeAllCoordinators` is used to take
checkpoint for `OperatorCoordinator` which is runing on JobMaster. So maybe we
can simply consider it as another kind of masterStates.
