New description:

 For starters, the timestamps are in the local timezone.  We can make that
 UTC

 Known problems:
  * When the websocket server panics (as in #29125), it writes the client
 IP address to the log:
    {{{
 2019/01/18 18:56:29 http2: panic serving X.X.X.X:YYYY: interface
 conversion: *http2.responseWriter is not http.Hijacker: missing method
 Hijack
    }}}
  * The broker logs the raw bytes of ICE answers:
    {{{
 2019/03/22 06:28:32 Received answer:  [XXX XXX XXX XXX ... XXX]
    }}}
