Title: --clone and --sockets flags -> zero-downtime deployments

When running deliver with the `--clone` flag, a new version of the same app will be pushed out, without touching the existing instance of the same app.

As an add-on to the above, there should be a `--sockets` flag that returns all ports & unix sockets that an app is using across all `$HOSTS`.
