Update Algeron Pact so it can be used as Service Virtualization

[lordofthejars]

Issue Overview

In complex microservices architecture, usually what you have is a consumer A that calls another provider B and at the same time, this provider B acts as a consumer of other services, let's call it Providers C and D.

So when you want to validate that Consumer A meets the expectations from Provider B, you write the contract test for the consumer by stubbing Provider B. But when you want to validate that Provider B also meets the expectations you need to stub its collaborators (Providers C and D). So in this case what you need is Service Virtualization to "mock" that services.

Ideally, you should not add a new technology for service virtualization, you could use the same used on the consumer side but in provider side.

Expected Behaviour

Use Pact Consumer stubbing capabilities in Provider to simulate the service dependencies of the provider.
