Proposal: Windows containers support

[joeapearson]

We have a dependency on Windows and having support for Windows containers in both Erlang and subsequently Elixir would be very useful.

Is this something that has been considered already? (I had a quick hunt through the issues on this repo and couldn't find much related to Windows but perhaps I'm missing something). Would others find this useful as a PR? We are going to spend some time investigating this in-house but we might have something suitable to contribute if so.

Here are some prototype images: https://github.com/avid-technology/docker-erlang-windows

They've only been very lightly tested so far but we're intending to use them in house.

IMO the nanoserver based images have great promise but they don't work yet out of the box, I assume because some dependency that Erlang is expecting is not provided for. If anyone is feeling adventurous we'd appreciate some expertise in identifying exactly what is needed.
