operator can auto-scale worker pods based on the tasks queue

Is your feature request related to a problem? Please describe.
Operator should be able to monitor tasks queue and if there are a lot of tasks in waiting state it should scale up temporarily worker pods because it means there are not enough of workers to process tasks( bottleneck).
Then operator should scale down worker pods once the task queue is empty (no bottleneck). Scaling down is important so pods do not consume resources in vain.

The issue names no files, tests, or entry points, so start by locating the operator's worker-pod reconciliation and task-queue integration. Done means worker pods scale up when waiting tasks indicate a bottleneck and scale down after the queue is empty, with the behavior covered by tests.
