support for writeOnly schema property

[equalspeterd]

User story.
As a schema designer, I want to use the openAPI writeOnly property to control schema request/response behavior.

Describe the solution you'd like
support:

schemas:
    secretType:
          properties:
            x:
              type: string
              description: present/allowed in read and write operations (GET, POST, PUT)
            y:
              writeOnly: true
              description: allowed for PUT/POST, not included in GET responses (for example)

Great idea! We are using openapi-sampler here so we can invoke the skipWriteOnly: true option.

We'll need to work with JSON Schema Faker to get their support up to draft 7. json-schema-faker/json-schema-faker#289
