Added Cloudformation Test Templates for 4.1 Testing

Per @tbeckham request, provided the cloudformation templates I use on several clouds.

I used the following type of images:
* [Ubuntu HVM Cloud Image](e.g. http://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img)
* [Ubuntu Paravirt Cloud Image](e.g. http://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64.tar.gz)
* [CoreOS Image](http://beta.release.core-os.net/amd64-usr/current/coreos_production_ami_image.bin.bz2) - I also did [a blog on this one](http://blogs.mindspew-age.com/2014/08/28/using-eucalyptus-4-0-1-cloudformation-to-deploy-a-coreos-docker-cluster/)
