Comment 19 for bug 1625402

What I understood from reading the glance config is that the option `work_dir` is used by the glance service for any async operation it has to do on images before the image is imported[1], this is not exclusive to the OVA import task. Thus the work_dir option may be set by the cloud operator for other reasons as well, not only to import an OVA image.
