Make the insights beacon.js load from a first party domain

When web analytics is enabled, Cloudflare embeds a call to this JS file

I would like to feature request that this script gets loaded on our domain as a first party request.

(Similar to how rocket loader will load from {mydomain}/cdn-cgi/scripts/*/Cloudflare-static/rocket-loader.min.js)

this would avoid the browser from having to accommodate requests to the 3rd party domains, making it load slightly quicker, and simplifying our content security policies.

if feels like a very quick win!
