Description RHOS Integration 2013-12-12 18:08:20 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/swift/+spec/object-cross-multi-container.

Description:

This can avoid duplicating objects across different containers and maintaining consistence of muliple version of cloned objects.
It is similar to shortcuts of an object which can be put in other containers.
When deleting an object, the object reference counter can be decreased 1. 
When the counter reaches zero, the object will be physically removed.
