POC - Consumer Testing with Cypress-Pact

[robg-test]

This PR uses the Cypress-Pact plugin to create a contract that can be used for a verification test

See: answerdigital/AnswerKing-CS#76

The goal of this PR is to define a Contract Testing milestone for the Test presence on the AnswerKing bench.

Work to follow on from this

• Upload the Contract as part of CI to a S3 Bucket, so that verifiers can find these files.
• Automate a Can-I-Deploy process that will invoke the Verifier Tests with the latest deployed code and the provided contract (Git SHA possibly)

• Run - npm run prettier to pass CI.
• We've changed the fake data so may need to adjust the example.json, so re-tests to make sure
• Needs rebasing.
