Document multi-architecture support and how to tag images to make it work

Docker Engine will pull the image that's appropriate for the host that's pulling the image, based on tags. We should have a topic showing how to tag images so this happens transparently.

cf. Microsoft Azure Container Registry Manages Docker Images

@JimGalasyn @mstanleyjones where to point or write this doc ?

Sorry, I don't understand the question you are asking. I think this would be a brand new topic.

@JimGalasyn @mstanleyjones will it be useful (https://docs.docker.com/engine/reference/commandline/tag/) ? It tells how to tag an image with respect to the repository and version
