I've love a PR! It shouldn't be much work, but I have a massive backlog at the moment. Happy to help out anyone who wants to pick it up.

• feat: Add metadata to a message request #12

interaction level metadata can be written with with_metadata on the consumer side, but it is not available at the provider side.

In pact-js now, which uses the pact_ffi, there is a new function providerWithMetadata in which the user is expected to return an object that returns not only the contents, but the metadata as well

• consumer side example
• provider side example

I imagine pact-ruby will need updates to accept to send the metadata in the message provider dsl, and for a consumer facing function to allow the user to provide the metadata to be validated
