[atlas] Proposal: Measure well-known CDNs,[CDN-HTTP]

Hello!

Disclaimer: I work for the Wikimedia Foundation.

I see some of the pushbacks on this proposal are about running measurements
towards commercial services.
One middle ground here might be to run such measurements towards non for
profits entities that run their own CDN.
Obviously I'm thinking of Wikipedia (and we would be happy to support such
a goal) but there might be others as well (eg. Internet Archives).

Thanks
