Document best practices for how to manage releases in production

[bfirsh]

We currently have some lightweight documentation about how to use Compose in production, but this could do with improvements:

• How to manage releases, particularly when deploying through the Docker Hub (e.g. in development build images, in production use image from Hub)
• A step-by-step guide to deploying a Compose app from dev through to production
• Some examples of how to deploy apps using init scripts
• Some examples of how to deploy apps using Swarm
• How to deploy apps on a single server (particularly useful for internal tools, etc)

Resources

• Examples of production Compose files

init scripts

and service-configs for systemd, that thing will take over. i thought of a command to generate these configs.

There's some previous discussion and requests in #93, #1264, #1730, #1035. I've closed those tickets in favour of this one, but linking to them for reference.
