    VMware: Refactor the image transfer
    
    The image transfer is unnecessary complicated and buggy. When
    transferring streamOptimized images we have to update the progress of
    the NFC lease to prevent timeouts.
    This patch replaces the complex usage of blocking queues and threads with
    a simple read+write loop. It has the same performance and the code is
    much cleaner. The NFC lease is updated with the loopingcall utility.

Title:
  VMware: NFC lease has to be updated when transferring streamOpt images

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Booting large streamOptimized images (>2GB) fails because the NFC
  lease is not updated. This causes the lease to timeout  and kill the
  image transfer. The fix is to call update_progress() method every
  60sec. This is also an opportunity to refactor the image transfer code
  and make it simpler.
