Block AMP analytics JS script

[vbanos]

AMP analytics is part of Google analytics. We need to block it for similar reasons. Current URL is

https://cdn.ampproject.org/v0/amp-analytics-0.1.js

but we have also seen:

https://cdn.ampproject.org/rtv/011906111828200/v0/amp-analytics-0.1.js

That's why we suggest the following pattern to block both:

*cdn.ampproject.org/*/amp-analytics*.js

In my experiments, blocking AMP analytics had the positive result of blocking some extra tracking JS:
