223 missing parent child relationships and type values

Changes Made

Fixed the endpoint import service so it sends the correct \_id values in POST requests. Refactored OAS adapter and SchemaBuilder so parent-child relationships between component param names are preserved, and parameters that share the same name are not overwritten as a result of flattening nested schemas. The functions __extract_param_properties and __dereference (from OAS adapter), and build (from SchemaBuilder) should be more simple and easier to read.

Expected Benefits

Should fix issues with parent-child relationships and type values (#223)

Example: (petstore-expanded.yaml)

paths:
  /pets:
    get:
      ...
      responses:
        '200':
          description: pet response
          content:
            application/json:
              schema:
                type: array
                items:
                  $ref: '#/components/schemas/Pet'
...
components:
  schemas:
    Pet:
      type: object
      allOf:
        - $ref: '#/components/schemas/NewPet'
        - type: object
          required:
          - id
          properties:
            id:
              type: integer
              format: int64
    NewPet:
      type: object
      required:
        - name  
      properties:
        name:
          type: string
        tag:
          type: string

Also fixes some bugs that the OAS adapter had:

Not preserving proper parent-child relationships for some nested schemas due to the partial flattening of the literal_body_params dictionary when adding param name literals. This caused the SchemaBuilder to generate incorrect \_id (parent ids) values, due to broken nested schema structures, as well as incorrect query strings.
Key collisions in the literal_body_params dictionary due to property names being used as keys. This caused some parameters to be overwritten if they shared a name with another parameter that happened to be added to the top level of the dictionary as a result of flattening.
Not being able to handle query parameters that used references in their schema definition

Testing

Updated SchemaBuilder and OAS adapter tests.
