download_stream_optimized_image() does not support preprocessing of image

Bug #1286708 reported by Vui Lam

Affects Status Importance Assigned to Milestone

Bug Description

As implemented is somewhat limited in that it takes the image_service/image_id and assumes it can use the image data obtain from the image server directly.
A recently use case has come up that requires some driver-specific processing of the glance image data to extract the actual stream optimized disk to be streamed to the server.
A more flexible alternative would be a function that takes a file-like object of the _actual_ data or a preprocessing callback.

Fixing this will unblock the fix in the nova vmwareapi compute driver to boot OVA images.
