[feature request] support Intel RDT

[CodeJuan]

Introduction of RDT

Intel Resource Director Technology (RDT) is a key feature set to optimize application performance and enhance the capabilities of orchestration and virtualization management server systems using Intel® Xeon® processors.

RDT consisted of two resource allocation sub-feature:

1. Cache Allocation Technology (CAT). CAT provides software-programmable control over the amount of cache space that can be consumed by a given thread, app, VM, or container. This allows, for example, OSs to protect important processes, or hypervisors to prioritize important VMs even in a noisy datacenter environment.
2. Memory Bandwidth Allocation (MBA). MBA provides indirect and approximate throttle over memory bandwidth (b/w) for the software. A user controls the resource by indicating the percentage of maximum memory b/w.

kernel requirement

1. CAT: 4.10+
2. MBA: 4.12+

TODO

To support Intel RDT, We need to add these things in Pouch:

• Pouchd
  • Design document
  • API integration
• runc: thanks for the greate contribution of @xiaochenshen, CAT PR was merged to master of runc. MBA PR is opened.
• Integration of Pouchd and runc
