Dockerfile validation

This WIP project focuses on automating the validation process of a Dockerfile by checking if the Dockerfile follows security best-practices.

• Uses conftest to parse the Dockerfile to get structured JSON data to be fed to Cue/OPA
  • conftest parse Dockerfile > <Dockerfile JSON File NAME> to convert Dockerfile to JSON
• validate-input-dockerfile.rego contains few policies written REGO to be used withh OPA
• dockerfile-schema.cue contains a Cue definition of a Dockerfile
• test-dockerfile.json contains a sample multi-stage Dockerfile in JSON format
• OPA Playground test link for the same policies
