Description RHOS Integration 2013-12-12 19:30:27 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/use-rbd-flatten-to-generate-glance-snapshot.

Description:

Currently, when we generate a snapshot using a rbd backend, firstly we should generate the image to a file system, then upload it to glance service, this costs a lot of time during the data transmission. 

In ceph, we can flatten our snapshot and make it independency with each other, and that will reduce lots of on data transmission.
