feat(web): record HTTP requests by route with latency for the traffic report

Browse Source 
Requests are counted by route pattern and status class with a latency
histogram (deferred requests until their answer goes out) and bytes sent.
The web server reports pending deferred requests and WebSocket clients, the
UGC server its worker threads.
