> FS allows setting {{SchedulingMode}} for leaf queues. Extending this to
> non-leaf queues allows using different kinds of fairness: e.g., root can have
> three child queues - fair-mem, drf-cpu-mem, drf-cpu-disk-mem taking different
> number of resources into account. In turn, this allows users to decide on the
> scheduling latency vs sophistication of the scheduling mode.
