Original change's description:
> Preload HSTS for the .foo gTLD.
> 
> This CL also adds unit tests for .foo preloading and updates two tests
> that were using http://foo as a test URL.
> 
> There are still other places in the code that use http[s]://foo as a test
> domain. If this change causes issues for them down the line, they should be
> changed to use foo.test or another domain under a test TLD:
> https://tools.ietf.org/html/rfc2606#section-2
