Fixing deployment issue in aiab

This patchset is to fix the deployment failure of aiab and other sites.
During the deployment, the airship-glance-test fails because the cirros
image URL i.e. "https://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img"
has multiple redirects while downloading the image. The rally test for
the glance never completes leading to deployment failure. This patch
set uses an alternative URL to fix this issue.
