> Users should have the ability to cancel a query on planning or execution
> stages.
> Firstly we should have API to retrieve the identifier of the query and API to
> cancel a query by the identifier.
> For cancel planning see {{AbstractRelOptPlanner.java:91}}, here
> {{CancelFlag}} is used to cancel planning loop. We need to pass it into a
> newly created context and bind its state with {{PlanningContext#queryCancel}}
> to break possible infinite planning loop. See also {{PlanningContext#unwrap}}
