commit 8d372e14b0240aa5735a7c0cf36e03e7b3344bd1
Author: Meng Zhu <[email protected]>
Date: Tue May 28 16:27:16 2019 +0200
Added methods to subtract `ResourceQuantities` from `ResourceLimits`.
This patch also makes `ResourceLimits` a friend class of
`ResourceQuantities` to achieve one-pass operation complexities.
Also added unit test.

> Currently, allocator only allocates resources for quota roles up to their
> guarantee in the first allocation stage. The allocator should continue
> allocating resources to these roles in the second stage below their quota
> limit. In other words, allocator should allow roles to burst above their
> guarantee but below the limit.
