Docker deployment documentation

[clayrisser]

So, I wrote a Docker configuration for Trails.js, including information on scaling with Docker. I would like to migrate this configuration and documentation into Trails.js. Where exactly would this fit in the main Trails.js documentation outline? My best guess right now is under Deploy -> Providers -> Docker.

Below are references to some of the discussions, configuration, and documentation about this subject.
