When API user requests status of a virtual task, we first need to find which virtual_task instance tracks given operation. While doing this we gather some info regarding the task, but we don't utilize it. Add virtual_task_hint that keeps info that was gathered during virtual task lookup and pass it to virtual_task's methods so the info doesn't need to be retrieved twice.
