Consumer Contracts (#83)

With this functionality you can have one centralized repository containing all contracts. This repo will have to produce a JAR containing all contracts. The layout of the repository can be arbitrary but some sensible defaults are assumed. The producer will be able to then download that JAR and produce tests and stubs from it.

fixes #38
