Node instance_info `image_disk_format` needs to be set to `raw` for
large raw images or the deployment may fail with a memory check error
or a full node tmpfs. Even when there is no error, without
image_disk_format=raw the image will not be streamed directly to disk.
image_disk_format is auto-detected and set by ironic for glance and
file sourced images, but this does not occur for direct HTTP based
images.
This change will set image_disk_format=raw when the URL file extension
ends with .raw, which is enough to support TripleO's conventions for
the overcloud raw image.

Since we've dropped support for Python 2.7, it's time to look at
the bright future that Python 3.x will bring and stop forcing
compatibility with older versions.
This patch removes the six library from requirements, not
looking back.
