integrate with Bugsnag services

[Nowaker]

Bugsnag is an error monitoring tool. When there's an exception, you get an e-mail, irc or whatever notification. No spam though - notification only after 1st, 10th, 100th exception. A nice dashboard lets you keep track of these exceptions, copy the stacktrace and create an issue in GitHub. Integration is easy-peasy. https://bugsnag.com/docs/notifiers/node

I'd like to code the integration myself. The config will get a new entry: bugsnagApiKey. When it's set, the proxy will submit the exceptions to Bugsnag. Please give a green light.

Sounds like a great idea, go for it!

We can provide Bugsnag with request metadata, e.g. URL, params or even the whole request. If we decide to do that, we will have #42 for free.
