Support or hints for registering and managing container images

[Startouf]

This gem looks very promising, I believe ECS container deployment is the next-gen deployment best practice.

I am wondering how you are building and registering your docker container images. What I have in mind is the entire deployment from building a new image with the current application state, and its deployment on the AWS cloud (and your gem currently only handles the latter)

I am expecting capistro deployments to handle the whole deployment, including registering the image with the capistrano revision number. So I am wondering how you are doing that, and if it could become a feature of the gem.
