Review comment:
How about we create new query plan nodes: `CommandResult` and
`CommandResultExec`
```
case class CommandResult(qe: QueryExecution) extends LeadNode {
def innerChildren = Seq(qe.analyzedPlan)
def output = qe.logicalPlan.output
}
case class CommandResultExec(qe: QueryExecution) extends LeafNodeExec {
def innerChildren = Seq(qe.executedPlan)
def output = qe.logicalPlan.output
}
```
then both UI and EXPLAIN can have pretty output.
