devstack-gate needs to be able to make an image that has pre-downloaded but not installed a sequence of packages. To support that, add a -d flag to install-packages to allow downloading but not installing. -d passes through on a dpkg install, and with this patch should be transformed to --downloadonly which is the yum version.
