Separate the meek bridge backing paid CDNs from the one we tell the general public to use
In source code and examples, we recommend !https://meek.bamsoftware.com/ (port 443) for use by the general public. But that's also the backing bridge for meek-azure, and it's rate-limited to reduce costs.
We should split it into two bridges (e.g. running on different ports). Rate-limit the one behind the paid CDN, because that's the expensive one. Make the other one unlimited (if someone else is paying the CDN fees, they can use all the bandwidth they want).
This will enable more people to use the default meek-azure at the same speed, while enabling people who set up their own to go fast.
