PrivCount proof of concept with existing statistics

Let's implement a proof-of-concept implementation of PrivCount that adds some noise to existing relay statistics, and then aggregates them.

This proof of concept will help us answer open questions, find bugs and unexpected issues, and get started on the metrics analysis. (But it doesn't need to be secure, because the stats are already public for each relay.)

We want to create a local proof of concept with counters set to 0 and 1. Then we want to create a minimal viable product with the relay bandwidth statistic. (If we want to show Guard, Middle, and Exit bandwidth, we'll need to make this statistic a histogram.)

Some of our detailed planning is here: https://trac.torproject.org/projects/tor/wiki/org/meetings/2018MexicoCity/Notes/PrivCount

These tasks are on the 0.4.1 roadmap for PrivCount and Sponsor V.

Let's review these tickets at the next meeting using our 041-proposed process.

They're on the roadmap, so the review should focus on ticket size and team capacity (and sponsor expectations).
