Description

Similar to YARN-3092, after YARN-796, now queues (ParentQueue and LeafQueue) need to track capacities-label (e.g. absolute-capacity, maximum-capacity, absolute-capacity, absolute-maximum-capacity, etc.). It's better to have a class to encapsulate these capacities to make both better maintainability/readability and fine-grained locking.
