> 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
