Comment 10 for bug 1584938

The merge proposal for this bug fix is now up: it both re-generates the simplestreams index after every image is uploaded, but also stores the metadata in Glance for re-use on the next run even if the simplestreams index is incomplete.

The Landscape tasks here consist of uploading a fixed version of simplestreams into our PPA for glance-simplestreams-sync.
