   I think the ExecutionContext should not a member of QueryStageScheduler, since we will support session context soon.
   
   ````
   pub(crate) struct QueryStageScheduler<
       T: 'static + AsLogicalPlan,
       U: 'static + AsExecutionPlan,
   > {
       ctx: Arc<RwLock<SessionContext>>,
       state: Arc<SchedulerState<T, U>>,
       event_sender: Option<EventSender<SchedulerServerEvent>>,
   }
   
   ````
