Allow to extend contracts & stubs

[marcingrzejszczak]

We will add a metadata field to contracts so that you can pass in custom data there. Example of such data will be extending WireMock stubs with webhooks, additional timeouts etc - whatever that is supported by WireMock. Users will be able to add their own metadata entries and register their own post processors.

Hello, where can I find webhooks example for producer side? And do we need to register webhook-extension on the consumer side? I'm having trouble setting all of this up. If there's some guide/tips somewhere it would be really helpful, thanks!

Here you have an example of such a contract
