Summary (updated)
-----------------
Refactored `struct Slave` in the allocator for better performance.
Bugs: MESOS-8986
https://issues.apache.org/jira/browse/MESOS-8986
Repository: mesos
Description
-------
This patch refactors the `struct Slave` in the allocator.
In particular, it addresses the slowness of computing
agent's available resources. Instead of calculating it
every time on the fly, this patch "denormalizes" the agent
available resources by updating and persisting the field
each time when agent's allocated or total resources change.

make check
In our simulation environment, we observed 16% allocator performance improvment
without quota, and 32% improvment when quota is used.
