Expose nova config option [workaround]/never_download_image_if_on_rbd
This exposes the nova workaround to disable downloading images from glance to rbd (vs a cheap COW clone) when nova-compute and glance are not backed by the same ceph cluster. Related nova change: I069b6b1d28eaf1eee5c7fb8d0fdef9c0c229a1bf Change-Id: I8329810d6c047c0d94e7b123e7cdc1263a7856cd
