Request: Go server codegen

First, forgive me if this is the wrong way to make this request. Thank you for the Go client generator. I would love to bring Swagger into my project (https://gokit.io) but to do that I'd need a Go server generator. I want to file the issue to register the interest and offer my help to review any PR someone could make — I don't have any Java chops, so I unfortunately won't be much help in making the PR :)
