Title:
  Large-ish image uploads timeout

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  Uploading large-ish (> 500 MB) images into Glance through the "Create
  Image" workflow times out.

  To reproduce:

  * Configure Horizon and Glance to live on separate machines
  * Upload a large-ish image via Horizon "From File" (This is I/O-dependant, but > 500MB seems to be enough on machines with 1GB links)

  Expected behavior:

  An uploaded file.

  Actual behavior:

  It uploads the entire file, then explodes with a 500 ISE. The image
  never gets uploaded.

  This is because the WSGI thread receives the entire file, THEN sends
  it to glance, blocking the view rendering until it's complete. If this
  takes too long, modern web browsers will disconnect, causing havoc.

  The "From URL" code path in Horizon (correctly, or at least not-as-
  wrongly) handles this in a separate thread, and has support for a
  whole bunch of AJAX-y update stuff as well.  Make Horizon do that.
