We need this for every devstack run now, so downloading it from github every time isn't the most awesome thing in the world. Add an extra variable EXTRA_CACHE_URLS which will be appended to the output of tools/image_list.sh. This way, these files will be downloaded during the daily nodepool build, but they will not be in the IMAGE_LIST and hence be considered as images to upload. Add a function get_extra_file which echos the path to a file given the URL. It will first check the cache at $FILES, and if not present download it. Update the documentation in image_list.sh to reflect what's happening. Move the defaults for etcd variables into stackrc, since it is a base service now.
