title: cloudformation does not attach the requested path param in api gateway
body: <p>I am trying to create api gateway in cloudformation. everything is good except when I specify path param url I can see it in the api gateway created. Here is my cfn code:</p>
  
  <pre><code>GetMethod:
  Type: AWS::ApiGateway::Method
  Properties:
    AuthorizationType: NONE
    HttpMethod: GET
    Integration:
      Type: HTTP
      IntegrationHttpMethod: GET
      Uri:
        Fn::Join:
        - ''
        - - "http://"
          - Fn::ImportValue: !Sub ${project}-${EnvironmentApp}-bn-user-endpoint-url
          - "/users"
          - "/{users}"
      IntegrationResponses:
      - StatusCode: 200
        ResponseParameters:
          method.response.header.Access-Control-Allow-Origin: "'*'"
        ResponseTemplates:
          application/json: ''
      RequestTemplates:
        application/json: ''
    RequestParameters:
      method.request.path.users: true
    ResourceId: !Ref UsersPathParam
    RestApiId:
      Ref: RestApi
    MethodResponses:
    - StatusCode: 200
      ResponseParameters:
          method.response.header.Access-Control-Allow-Origin: true
  </code></pre>
  
  <p>If you noticed in the code above I specifically ask for path param called users:</p>
  
  <pre><code>RequestParameters:
      method.request.path.users: true
  </code></pre>
  
  <p>Also, you can see the created API gateway that has no path param set in the attached image.
  Any ideas?</p>
