Fix display of images in Rebuild Instance

The image list in Rebuild Instance is constructed from (id, name)
pairs. As the name is a string, the transform function is never called
unless image name is None. In that case it crashes the view.

This change:
  - Builds the image list with (id, image) so the correct thing
      is passed to the transform
  - Corrects the size/name attributes
  - Handles None display name (displays id instead)
  - Set the name of one of the public images in glance_data.py to
      None so errors like these are picked up in the future.

Common keystone version fallback

If OPENSTACK_API_VERSIONS["identity"] was not set in local_settings.py,
django_openstack_auth and horizon had their own fallback method which
did not necessarily fallback on the same version and was leading to
discrepancies and erratic behavior.

Refactored in order to use the same fallback method defined in
django_openstack_auth.utils
