Automate best practices for production

This could be a collection of scripts, or packages of various formats (Docker, Flatpak, `.deb`, etc.). Broad coverage of most of the production environments probably necessitates multiple formats, though we should prefer a solution that covers as many as possible in as few variants as possible. This will reduce the cost of maintenance and the chance of error in one or more of them. Googlers, see go/amp-packager-deployment-requirements for more info.
