Description

The scheduler needs to understand app/task priority and make proper decisions while allocating resources. I think we don't need to introduce a very complex model when defining priorities, e.g supporting both queues, app, and task level priorities, it will be hard for users to consume. Instead, we need to find a clean, straightforward approach to handle priorities.
