> This provides practicality of manipulating resource queues in real
> environment. User can alter a resource queue on demand any time without
> waiting for releasing all corresponding queues' workload.
> hawq_rm_force_alterqueue_cancel_queued_request guc variable is introduced,
> default value is 'true' that means alter resource queue statement can force
> resource manager to cancel all resource requests that can not be adjusted to
> fit new resource queue definitions. If it is set 'false', the alter resource
> queue statement will be cancelled to avoid canceling any queued query
> resource requests in resource manager.
