Automatically generate a Docker image for a project based on its dependencies

[alex-ketch]

Currently projects are executed in either a generic Docker image, or a manually created one that has to be configured for the project by the user.

Instead we'd like to use some of our existing tooling such as Dockta/Nixta and automatically generate and configure a project to use a custom Docker container which we will create based on the project's "requirements/package.json/Dockerfile" file.
