Sometimes the cirros image fails to upload to glance. Its not clear whether this is a problem with glance, the backend glance is using, or the server from which the image is being pulled. Also this task is not retried.
Example failure:

===========================
In order to pin point the problems, I propose that we split the cirros image creation task into two tasks:
1) Download the cirros image from a public repo
2) Upload the image to glance
This isn't as straightforward as I'd thought as the OSA glance library doesn't support uploading a local file, and adding that functionality is not made easier by the python glance client api.
