Brian Rosmaita 4a5ff4eb75 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.)

`Bug #1898075
<https://bugs.launchpad.net/cinder/+bug/1898075>`_: When Glance added
support for multiple cinder stores, Images API version 2.11 modified
the format of the image location URI, which Cinder reads in order
to try to use an optimized data path when creating a volume from an
image. Unfortunately, Cinder did not understand the new format and
when Glance multiple cinder stores were used, Cinder could not use
the optimized data path, and instead downloaded image data from
the Image service. Cinder now supports Images API version 2.11.
