Automatic CDN configuration for Pages

Description

Pages is awesome, but serving content to the world from a single GitLab server isn't great for speed. A Content Delivery Network (CDN) copies the static content to multiple servers spread around the world to reduce network transport time to the end-user.

Proposal

Provide CDN for Pages, automatically, perhaps using free CloudFlare integration.
