This method is currently missing. Here is just a basic interface to pass type checks. If you'd help me figure out how to depend on Node TSD, I'd try to make signature more correct, and return http or https response instead of just `any`. Also planning to add `params` object interface.
first batch: the easy pickings
- as per https://github.com/borisyankov/DefinitelyTyped/issues/115
- added DT headers (scraped creators from git history)
- added tests
- some modifications
- added CONTRIBUTORS.md for the substantial defs (>50 LOC)
