Make list_images.sh emit the etcd3 tarball
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.
