Move image downloads into resource downloader containers

Move the download of the IPA and CoreOS image download into
containers. These containers can be used to download the images
for ironic running on the bootstrap and master nodes.

When downloading images on the master nodes the container can be
instructed to get the image from the bootstrap http server by setting
CACHEURL=http://172.22.0.1/images
