> Completed applications remain linked to a queue and never cleaned up. This is a similar problem as we have seen in YUNIKORN-1440.
> The problem is however larger than just keeping it linked and not cleaning up:
> * the completedApplications map in the queue is not safe for appID reuse as the map key is the application ID without suffix.
> * a dynamic queue is removed when empty: a newly created queue with the same path does not have any history which is incorrect
> * the completedApplications map in the queue is never cleaned up
