Create Builder class for Proof Request

[wip-abramson]

Description

The proof request object required by the Swagger-API is a large JSON object specifying the attributes their constraints that a verifier will accept. E.g. attribute x from schema y and issuer did z. Currently, the basic controller provides no support to help the application developer construct these proofs.

The design of a Builder class should be explored and developed to make this easier.

Are you interested in working on this improvement yourself?

• No, but I am happy to support someone who is.

Running through the aries-fl project should give some more context to how this will add value - https://github.com/OpenMined/PyDentity/tree/master/projects/aries-fl
