Propose better bridge usage statistics
In #3261 (moved) I found that the way how bridges report their statistics to the bridge authority is not the reason why our bridge usage numbers are so unreliable. It's the way how we derive user numbers from unique IP addresses which is totally broken. We should try an approach that's similar to how we count directory requests on directory mirrors.
There are a few substeps necessary to come up with better bridge usage statistics:
- Write a proposal for new bridge statistics based on counting directory requests per day and country. (4 points)
- Implement the proposal, get it in mergeable state, and test it on three own bridges that don't publish the new statistics to the bridge authority yet. (4 points)
- Evaluate whether the new statistics can improve our user number estimates, and if so, enable reporting to the bridge authority and prepare deployment on all new bridges. (6 points)
