Proposal: Add template for golang functions

[0xdevalias]

Expected Behaviour

Currently there are templates for: csharp, node, python, ruby. It would be great to have a go template as well.

There is a golang base function in the main FaaS repository that can be used as a base. Though this could be improved even more using Docker multi-stage build syntax, and separating the golang compilation environment from the run environment (eg. static compilation)

The faas-cli new command would also need to be updated to include this new template.

@rgee0 how practical is it to template with Golang? Should we generate a "Dockerfile" version with all the assets in the handler folder? I have the impression third party dependencies are often required beyond what you can pull with vndr or similar.

[alexellis]

I agree that we can make Hubstats multi-stage and the base Golang sample. Can someone do that initially?

[rgee0]

@alexellis initial thought was that Golang is potentially closer to the .exe use cases. However, if we are going to include the build in the template then I think we head into the territory you're alluding to. I'm not experienced enough with vndr to comment on that specifically. What fuels you impression?

[alexellis]

Here's an idea - let Golang generate a Docker build. That way it's still a template but you are expected to hack on the Dockercon etc

This seems to have landed in #145 with some additional work in #146
