Description

A new issue was discovered while fixing YUNIKORN-2465. This also results in growing memory usage in case of long running applications.

When a pod reaches a terminal state (Success / Failed), we send an update request from the shim to the core (Task.releaseAllocation()). However, we only discard the allocation itself and we don't do anything about the ask. It is kept inside the Application object until it becomes Completed.
