Title:
  no size check when using http to create an image

Status in OpenStack Image Registry and Delivery Service (Glance):
  Fix Released
Status in Python client library for Glance:
  New

Bug description:
  if I create an image from file and use --size which is smaller than
  the image on file we would fail with the below error:

  root@opens-XXXX ~(keystone_admin)]# glance image-create --name rhevm_image --disk-format qcow2 --container-format bare --file /tmp/39f89a6a-7fbb-43c0-a5ea-19b271f51829 --size 1
  Request returned failure status.
  400 Bad Request
  Supplied size (1) and size generated from uploaded image (1440612352) did not match. Setting image status to 'killed'.
      (HTTP 400)

  but if I create an image from http and use a smaller size the image is
  created:

  [root@opens-XXX ~(keystone_admin)]# glance image-create --name human
  --disk-format qcow2 --container-format bare --location http://XXXXXXX
  --human-readable --size 1

  if size is too small we should not allow the create of the image from
  http as well
