Bug Description

Glance 2.11 changes the format of a "cinder" URI [0]. The old-style glance location URI for image data in a cinder-backed glance_store is this:
cinder://<volume_id>
The new style in the case of multiple glance stores is:
cinder://<glance_store_name>/<volume_id>

The current way we're extracting the volume_id from the URI (see [1,2]) is going to give us
<glance_store_name>/<volume_id>
to work with as a "volume ID" for cinder, which won't match with any actual volume_id unless we process it some more.

The fix needs to be able to handle both legacy and new-style formats.

I've been testing this, and while Cinder does indeed not understand the 2.11 cinder:// urls, this bug doesn't "break" Cinder because when Cinder can't find the volume containing the image, it just downloads the image from Glance and creates the volume that way. So while the bug prevents Cinder from using the optimized work flow, it doesn't prevent creation of volumes from images.

Support Images API v2.11

    Glance has changed the format of the cinder URIs in image locations
    so that they can look like
       cinder://glance-store-name/volume_id
    in addition to the legacy format
       cinder://volume_id

Change the cinder code so that it can handle both formats for
reading. (We only need to write the legacy format.)
