VMware: Fetching images from Glance is slower than it should be

[Arnaud Legendre]

Ran an experiment with a 1.5GB file on a very basic devstack setup:
glance download | curl PUT: 2.5min
nova code: 4min

Customers have reported similar concerns.

    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.
