Title:
  Image segments not deleted from swift when size >  image_size_cap

Status in OpenStack Image Registry and Delivery Service (Glance):
  Fix Released

Bug description:
  If we set image_size_cap to 10 Meg:

  image_size_cap = 10485760

  And set the swift_store_large_object_size to 4 Meg:

  swift_store_large_object_size = 4

  And set the swift chunk size to 2 Meg:

  swift_store_large_object_chunk_size = 2

  Then upload 10485761 bytes in a way that the image size is not known
  beforehand:

  $ glance  --os-image-api-version 1 --os-username glance --os-password
  XXX --os-tenant-name service  --os-auth-url http://localhost:5000/v2.0
  image-create --name "x1" --is-public=True --container-format ami
  --disk-format ami < /tmp/10485761.fifo

  $ cat /tmp/10485761 >> /tmp/10485761.fifo

  Request returned failure status.
  400 Bad Request
  Denying attempt to upload image larger than 10485760 bytes.
      (HTTP 400)

  Once the operation has completed the swift segments are still present:

  $ swift   --os-username glance --os-password XXX --os-tenant-name service  --os-auth-url http://localhost:5000/v2.0 list glance | grep d723a481-fdb2-4576-9340-5cab95c83ac1
