feat(generators): Pass back result from provider state setup URL #53

[slt]

Addressing issue #49

• Adds support for all generators from v3 spec and the ProviderState generator.
• ProviderState generator saves the results from the --provider-state-setup-url and templates them into a value using an expression.

Requires pact-foundation/pact-ruby#273 & pact-foundation/pact-support#97

I based this around @hhhonzik's previous pull request here

I ended up moving to the rust standalone provider verifier, it has all of these features implemented already as well as the v3 and v4 pact specifications

https://docs.pact.io/implementation_guides/rust/pact_verifier_cli

Given its standalone and almost a drop-in replacement, I don't see why it wouldn't be preferred over this one. I would suggest that the docs of this project are updated to point to it instead.

I'm not a ruby developer and I only did these pull requests to unblock myself, I'm happy for them to be merged if they help anyone else but I don't have the capacity to support this work moving forward

Hey thanks @slt sorry for the delay in looking at this.

You are correct, the rust is the preferred going forward and this is considered to be legacy

thanks for your support and work in pact-ruby as well, especially as a non ruby developer (it is how I started with Pact)

Beth hasn't had a-lot of bandwidth for looking at these PR's and as we can utilise the FFI library in Ruby, we may go down that route for v3/v4 support but not decided yet. Great that you found the rust library and that will sort you out!

There is probably value in keeping the PR, however if you want to close it we can always re-open it in the future.

closing in favour of #125, thanks Steve
