As a Cluster admin, it would be nice to be able to access Gluster functionality without needing their command-line tool. We could wrap the CLI in a REST API or something similar. This would enable me to programmatically / remotely create, mount, or resize storage.

A quick / hacked prototype of similar functionality can be found here: https://github.com/kshlm/gluster-rest

This story is complete when we can decide either to leverage the above code, or we generate/write our own API.
