> If the executor configuration changes while a query is waiting to be admitted, we need to reschedule it. The current behavior tries to run it as is which will then fail. To achieve this, we should call Scheduler::Schedule() from the AdmissionController and then re-schedule if necessary. We need to think about ways to detect changes to the executor configuration, but a simple hash might be good enough.
