MSISDN api and testing

The MSISDN api can be pretty difficult to understand. There are a whole bunch of different pieces (server-side and client-side) to the puzzle.

https://github.com/mozilla-services/msisdn-gateway/blob/master/API.md is currently the best documentation where this api and its flow is described.
This all ties in with the Firefox Loop project.
