add ExitPortStatistics graph
Since Relay Operators can opt in to report their exit usage per port, show some metrics about it.
Add ExitPortStatistics graph to the relay page of Relay Search Details for: Exit
And globally?
Exit relays only. When this option is enabled, Tor writes statistics on the number of relayed bytes and opened stream per exit port to disk every 24 hours. Enables exit relay operators to measure and monitor amounts of traffic that leaves Tor network through their exit node. If ExtraInfoStatistics is enabled, it will be published as part of extra-info document.
This will help us answer questions like:
What percentage of Exit Traffic is "Website" only traffic?
What is the biggest share of Traffic per destination port? Not torrents!
Which exit country does share the most Traffic for which destination ports?
