[csharp-dotnet2] Generated code path for client does not match package name

Command line used for generation

java -jar ./swagger-codegen-cli-3.0.15.jar generate -i MyProgram.yaml -l csharp-dotnet2 -o "client" --additional-properties packageName="MyProgram.Api" clientPackage="Atos.Tec.MyProgram.Api" modelPackage="Atos.Tec.MyProgram.Api" apiPackage="Atos.Tec.MyProgram.Api" invokerPackage="Atos.Tec.MyProgram.Api"

Description

I want all generated files to have the namespace Atos.Tec.MyProgram.Api, but the package Name should be shorter MyProgram.Api. For some reason the clientPackage parameter changes the namespace (correct) and the path of the generated files (wrong).

Swagger-codegen version

swagger-codegen-cli-3.0.15.jar

Steps to reproduce

1. Use any example openapi Spec
2. Run the above command with that spec and check the generated folder structure.

Suggest a fix/enhancement

It should use the same path as all other parameters (so without Atos/Tec).

Start by reproducing the command with swagger-codegen-cli-3.0.15.jar and an example OpenAPI spec, then inspect the csharp-dotnet2 generator's generated folder structure. Done means the namespace remains Atos.Tec.MyProgram.Api while the generated path uses the shorter MyProgram.Api package path without Atos/Tec.
