Consider adding a logger to the context object

[ceejbot]

Specifically so the logger can have a request id associated with it automatically. This would enhance out-of-the-box logging with a pattern we'd like to support.

Hm, I still dislike that this would lead to baton passing / encourage improper use of bole. We might restate this issue in terms of end goals: the request id should end up in log lines. It might be possible to do this without baton-passing by leaning on honeycomb's use of async-hooks?
