Autoscaler Standalone should clean up them if some jobs cannot be fetched
anymore.

- [FLINK-34212][autoscaler] Autoscaler Standalone cleans up stopped jobs to
prevent memory leaks
- We assume one job is stopped when one job is fetched in the last control
loop and it cannot be fetched in current control loop.
