per-project-user quotas support

Registered by Kylin CG on 2012-04-18

Currently nova supports per-project quotas, that is, users under a same
project(tenant) have identically the same quotas set. It's not enough
when we want to limit user's use of cloud resources.
Thereby we present per-user quotas.
A user's quotas is defined in association with a specific project.
The sum of all users' quotas under a same project should not exceed
the quotas of the project.

The following aspects will be covered
  - User quota is a sub-division of a project quota
  - If user quota is not setted, the usages of a resource of all users will be limited by project quotas, that is, it's compatible with the current project-quotas.
  - The usage of a resource will be limited by the user quota which is under a specific project quota, if it was setted.
