[GO] Server, no docs and empty responses

Description

Go server does not have /docs and does not return responses. I'm sure you are aware of this, but it's not clear to a developer which features are supported on each server. Maybe you need a feature grid?

Swagger-codegen version

Steps to reproduce

Go to: https://editor.swagger.io

Using the PetStore example, then click:

• Generate -> nodejs-server
• Generate -> go-server

Then run each server and go to:
http://localhost:8080/docs
http://localhost:8080/v2/store/inventory

Notice how NodeJS version returns a response, but Go server version does not.

Suggest a fix/enhancement

First create a feature grid, to show which servers support which features. Second add the features when possible :)

Start by generating the PetStore example as a go-server from editor.swagger.io and compare its /docs and /v2/store/inventory behavior with the nodejs-server. Define the supported-server feature grid, then verify which missing documentation and response behaviors are expected to be addressed.
