should catch GlanceMetadataNotFound in creating cgsnapshot

[wanghao]

When creating cgsnapshot, Cinder will copy bootable volume's image metadata to snapshot, but if the volume don't have image metadata, Cinder should catach GlanceMetadataNotFound and let it pass, but now Cinder only catch CinderException and raise it.

This is inconsistency with creating snapshot. So we should fix it.
