> The other half of the current scheduling logic is the management of slot sharing and
is located in the SlotPool. We need to extract this logic into our new Scheduler component
from the previous step. This leaves us with a simpler SlotPool that mainly cares about obtaining,
holding, and releasing slots in interaction with a ResourceManager. The new Scheduler can
now identify slot sharing groups and interacts with the SlotPool.
