Can you add a test for the logger?

I think the best way to test it would be to use the nock package. There is a bunch of examples in dd-trace already of how to use it. Basically it takes a URL to intercept, and can trigger some expect() calls to ensure the log body that is sent adheres to the expected shape.

[Qard]

Generally LGTM with some minor suggested improvements.
