Which problem is this feature request solving?

CLI should be able to download plugin binaries from a given config separately, without requiring authentication and proceeding further. This would help to prepare self-contained Docker images where the cli and required plugins are ready to go.

Describe the solution you'd like

Just like the migrate command, we would have a download command where a given config is processed, cq-dir is evaluated and missing binaries are downloaded.
