Bug Description

If we use several glance-api instances and store images in cinder than during creation several VM nova-compute request image from glance-api. For increasing speed of VM creation we allow multiattach for volumes with images. Looks like glance_store use attach/detach workflow v1(https://github.com/openstack/cinder/blob/master/doc/source/contributor/attach_detach_conventions.rst) not attach/detach workflow v2(https://github.com/openstack/cinder/blob/master/doc/source/contributor/attach_detach_conventions_v2.rst). In this case glance_store can not detach volume because it does not have attachment_id.
