Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/framework-for-contributed-storage-systems.

Description:

At times contributors wish to add storage drivers to Glance.  No matter how good the code is when it enters there is always a concern of potential bit-rot.  We also must concern ourselves with all of the dependencies related to a new storage driver.

Further, those wishing to use different storage system backends must wait until a patch is reviewed, then approved, then released.

It would benefit the community if we were to have a framework for adding storage drivers, as their own packages, to a glance deploy.  While I beleive that this is possible today, I think that it would be better if we had an contrib section in glance where various storage drivers were added.  These drivers would be part of the glance code base, but not installed by default.  This would serve two purposes, it would thin out a default/basic deploy and it would serve as an example of how to create a storage driver package.
