The short answer is you can't use a CDN. CDNs are a hole in the HTML Imports story atm.
Imports need to resolve to the same URL to be de-duplicated correctly by the browser. Serving the same component from two different URLs won't be deduped properly. This is why we recommend bringing in components locally using Bower and serving them from your own setup. IMO, this is one of the biggest issues Polymer and the standards process needs to solve. It prevents the most convenient reuse of components.
