Glance now has ability to configure multiple stores at a
time. To use this feature in cinder for uploading volume to image, operator
need to define a new field named 'image_service:store_id' in the
volume-type extra-specs. At a time of volume upload to image request, if
'image_service:store_id' is present in the associated volume type, then
image will be uploaded to specified 'store_id'. The value 'store_id' is
nothing but store identifier defined in glance-api.conf. If the value
of 'image_service:store_id' is null or not set in volume-type then the
image will be uploaded to default store in glance.
