Implement all FFI methods relating to Interaction

[JP-Ellis]

Description

• Implement all missing methods for the Interaction class. The scope of 'all' here relates to the methods exposed by the FFI which typically either: construct a Interaction (returning an InteractionHandle); or, take an InteractionHandle as an argument and modify the underlying Pact
• Ensure all new methods are systematically unit-tested.

Motivation

Initial work implementing the Interaction class was done as part of #410; however, the scope of the PR was limited to a MWE to ease with the review and ensure that the more substantive/foundational parts can be reviewed and the finer implementation details can kept separate.

Have you tried building it?

Continuation of prior work

Self-service

• I'd be willing to contribute this feature to Pact Python myself.
