Same name for all models defined inline for responses

[ashwini-desai]

Problem:
For paths with more than one inline response schema defined, names for all models are generated the same.
Eg:

/pets:
    post:
      summary: Create pets
      operationId: createPets
      tags:
        - pets
      requestBody:
        description: 'Create pets'
        content:
          application/json:
            schema:
              type: array
              items:
                type: object
                required:
                  - id
                  - name
                properties:
                  id:
                    type: integer
                    format: int64
                  name:
                    type: string
                  tags:
                    type: array
                    items:
                      type: string
        required: true
      responses:
        '200':
          description: list of pets created
          content:
            application/json:
              schema:
                type: array
                items:
                  type: object
                  required:
                    - id
                    - name
                  properties:
                    id:
                      type: integer
                      format: int64
                    name:
                      type: string
                    tags:
                      type: array
                      items:
                        type: string
        default:
          description: unexpected error
          content:
            application/json:
              schema:
                type: object
                required:
                  - code
                  - message
                properties:
                  code:
                    type: integer
                    format: int32
                  message:
                    type: string

In this path above, two models for responses are generated - one of type kotlin.collections.List<ShowByPetIdResponse> and another of type ShowByPetIdResponse.

Tech notes:
Currently the only mandatory field which can help us differentiate responses are the http statuses(200, 300..etc) or default.
