[REQ] Better Structure for Go Server Project

Created by: zhoub

Is your feature request related to a problem? Please describe.

Hi,

Now the go-server creates a project like this

│   main.go
│   Dockerfile
│   .openapi-generator-ignore
│
├───go
│       model_user.go
│       api_default.go
│       routers.go
│       logger.go
│       README.md
│
├───api
│       openapi.yaml
│
└───.openapi-generator
        VERSION

Describe the solution you'd like

Shall we create a structure similar to the go-swagger generates folders.

cmd/<server's name>/main.go
models/<all models>

Thanks !
