Add rax flex iad3 to clouds.yaml and cloud management

This adds the new rax flex iad3 region to our clouds.yaml files and
configures the cloud with ssh keys, networks, and security groups. This
is the first step in getting this cloud enrolled with zuul. Once this is
done we can boot a new mirror, then add the cloud to our resource list
in zuul-providers.
