[SPARK-22252][SQL][followup] Command should not be a LeafNode ## What changes were proposed in this pull request? #19474 partially reverted #18064 but accidentally introduced a behavior change. `Command` extended `LogicalPlan` before #18064 , but #19474 made it extend `LeafNode`. This is an internal behavior change as now all `Command` subclasses can't define children, and they have to implement `computeStatistic` method. This PR fixes this by making `Command` extend `LogicalPlan` ## How was this patch tested?
