"""If deleting images in 'saving' status, storage quota is overcome by
user because images in deleted state are not taken into account by
quota. These image files should be deleted after the upload of files
is completed.
Scenario:
1. Set 'file' storage on glance-api.conf
2. Set 'user_storage_quota' to 604979776 in glance-api.conf
(a little more than the size of the image) and restart glance-api
service
3. Run 5-min cycle which creates image, wait 2 sec and then
deletes it in "saving" status (and in any other status if any) on
every iteration
4. After the end of cycle wait until the upload and deleting images
is completed
5. Check that images statuses are "deleted" in mysql database
Duration 5m
