Add CDN Level3

Hello,

I’m currently using Level3 CDN and it’s not detected :-/

It can be detected by CNAME ending with “.fpbns.net.”

If you have any question, you can contact me.

Thanks !

Thanks. Just added to the code and it will probably go live within the next week on the public instance (whenever a new update gets pushed): https://github.com/WPO-Foundation/webpagetest/commit/b9e50e8a35de04e045e9e7cea59f70767a17e942
