Rajat Dhasmana 6a17e4e2ba Fix LP#2054575
This patch contains a squash of two commits:

COMMIT 1:

Make location URL compatible with cinder backend

While adding location to an image, cinder sends location url as
`cinder://volume_id` for single as well as multistore which is
incompatible with glance multistore and store throws
InvalidLoctation error.

Modifying the location url to be compatible with multistore as
`cinder://store_id/volume_id` to avoid Invalid Location error.

COMMIT 2:

Fix: optimized upload volume in Cinder store

When Glance is configured to use Cinder store and we upload
volume to Glance in the optimized path, it fails with
InvalidLocation error.
This happens because Cinder is not aware about the store
in which we will create the image and supplies the old
format URL i.e. cinder://<vol-id> whereas Glance expects
new location format i.e. cinder://<store-id>/<vol-id>.

Glance has code to update the format from old location format
to new location format but it isn't triggered in case of
old location APIs.

This patch adds the context to the update store ID request
which calls the Cinder store to provide the updated location,
hence fixing the optimized path for upload volume to image.

`Bug #2054575 <https://bugs.launchpad.net/glance/+bug/2054575>`_:
Fixed the issue when cinder uploads a volume to glance in the
optimized path and glance rejects the request with invalid location.
Now we convert the old location format sent by cinder into the new
location format supported by multi store, hence allowing volumes to
be uploaded in an optimized way.
