need for them to be called directly.

This introduces a few important changes to the interaction definition:

- Addition of `response_headers`
- Support for the response status code through either the `response` or
  `status` kwargs
- Combining the response content type and body to reflect the same logic
  as with the request body and content type.
- A new `add_to_flask` method (akin to `add_to_pact`) which defines the
  interaction for a Flask app.

arguments between the test suite, and the Flask app running in a
separate process.

The initial implementation of the compatibility suite spun up and down
the Pact Broker for each scenario, which also resulting in flaky tests
in CI.

This refactor uses a session pytest fixture which will spin up the
broker once, and keep re-using it. Functionality to 'reset' the broker
between tests has also been added.
