Provide a way to tag logging per request.

[amol-]

Currently when logging there is no way to know which request a log line belongs to, we might want to add a way to allow this. If this is not possible through standard logging module (which I suspect) we might provide (and use everywhere) a tg.log that logs the request id too when it's available.

%(thread)s @ %(process)s format might be a good enough solution for 90% of users. Should it be in the default quickstart?

Yeah, that would perhaps be helpful. Especially if the thread can be tracked all the way from the request comes in. Once you know it, it is quite trivial to add. But having it in the quickstart would remove the need for knowing it.

Something with ordering like %(process)s - %(thread)s would probably be more natural.
