Description

Background: We are planning to implement a new architecture in the Kubernetes/ingress-nginx project, and we found that pkg/pubsub works well for our needs. But we don't want to vendor the full docker repository. Start this discussion to move it to a standalone repository. Thanks!

The pkg/pubsub package is a small package and, looking at git history, has low maintenance (last changes were made 2 years ago). Similar to (e.g.) the https://github.com/moby/sys and https://github.com/moby/term packages, we can consider moving the package to its own repository, to allow easier consumption of the package without having to pull in the whole docker repository
