----------------------------
    Comment: was deleted

(was: For [~gyliu]'s proposal on {{requestResources}}, I think that would be a long term solution for us; maybe we can re-visit it in "allocator refactor" ticket. 

[~alexr], for the "granularity", suggest to make the default value to be {{total resource/framework #}} of each resources. But one concern is if lots of frameworks, the allocator's performance will be downgrade. Maybe we can have a try to see the performance. Any comments.)

> The built-in allocator performs "coarse-grained" allocation, meaning that it always allocates the entire remaining agent resources to a single framework. This may heavily impact allocation fairness in some cases, for example in presence of numerous greedy frameworks and a small number of powerful agents.
> A possible solution would be to allow operators explicitly specify granularity via allocator flags. While this can be tricky for non-standard resources, it's pretty straightforward for {{cpus}} and {{mem}}.
