.NET CDK ignores integration options & method responses in API Gateway methods

[RomainMuller]

Regardless what is set in MethodResponses and IntegrationOptions, the cdk synth command output cloud formation wouldn't have those configuration as part of its Cloud Formation output when using cdk for .NET.

Here is the .NET C# code, you can see there are some configurations related to Status code 200

            var serviceResourceMethodResponses = new Dictionary<string, object>[] { new Dictionary<string, object>()};
            serviceResourceMethodResponses[0].Add("StatusCode", "200");
            serviceResourceMethodResponses[0].Add("ResponseModels", new Dictionary<string, string> { { "application/json", "Empty" } });

        var integrationResponseOptions = new IntegrationOptions
        {
            IntegrationResponses = new IntegrationResponse[] { new IntegrationResponse {
                        StatusCode = "200",
                        ResponseTemplates = new Dictionary<string, string> { {"application/json", "" } }
            }}
        };

            var serviceGet = new CfnMethod_(this, "serviceGetId", new CfnMethodProps
            {
                HttpMethod = "GET",
                Integration = new IntegrationProps
                {
                    Type = IntegrationType.AwsProxy,
                    Options = integrationResponseOptions,
                    IntegrationHttpMethod = "GET",
                    Uri = $"arn:aws:apigateway:{region}:lambda:path/2015-03-31/functions/{DemoAPIG.FunctionArn}/invocations"
                },
                ResourceId = serviceResource.ResourceId,
                ApiKeyRequired = false,
                AuthorizationType = "AWS_IAM",
                RestApiId = apigForWorkDocsGoService.RestApiId,
                MethodResponses = serviceResourceMethodResponses
            });
            serviceGet.AddDependsOn(serviceResource);

Here is the Cloud Formation Output from cdk synth command and no integration configuration nor the method response configuration

  serviceGetId:
    Type: AWS::ApiGateway::Method
    Properties:
      HttpMethod: GET
      ResourceId:
        Ref: serviceResourceId
      RestApiId:
        Ref: apigForDemoServiceId
      ApiKeyRequired: false
      AuthorizationType: AWS_IAM
      Integration:
        IntegrationHttpMethod: GET
        Type: AWS_PROXY
        Uri:
          Fn::Join:
            - ""
            - - arn:aws:apigateway:ap-northeast-1:lambda:path/2015-03-31/functions/
              - Fn::GetAtt:
                  - DemoAPIGId
                  - Arn
              - /invocations
    DependsOn:
      - serviceResourceId
    Metadata:
      aws:cdk:path: nrt-prod/serviceGetId

@eladb looks like you were poking on this one. Is this .NET specific, or are you doing something in the jsii core to address it?

I was thinking I'll have time this week to take a look but haven't had a chance, so this needs a bit of investigation (and also validate that it still repros, since we did make some changes that may help this).
