Reproducible container builds via explicit version annotations

[negrinho]

It is my understanding that, in its current form, the container builds are not really reproducible as they use the most recent versions available. This is great in many cases, but undesirable in many others, e.g., if you want to build the exact same container that you would one year ago. Having explicit versions would mitigate this. Have you consider adding explicit version annotations in some form?

@negrinho Sounds great. We don't have a perfect solution to this yet. Related contributions are appreciated.
