Invalidate artifacts on CloudFront more reliably

[brson]

We're only on cloudfront because it was an easy way to set up HTTPS, but it's been a huge pain because our files are always out of sync. Since for #20629 we probably need at HTTPS proxy anyway, we should just do it ourselves with nginx.

Nominating because the cdn sync issues tend to cause a lot of confusion.

Is there a workaround for this? Currently getting hash mismatches on OSX:

@wildlyinaccurate the workaround is 'wait a while' 😦

Managed to get it installed via Homebrew on OSX. I realise that's not very helpful for anybody on Linux, though...
