Since the repo is no longer just the registry, we are moving the registry web application package out of the repo root into a sub-package. We may break down the registry package further to separate webapp components and bring the client package under it. This change accomplishes the task of freeing up the repo root for a distribution-oriented package. A stub doc.go file is left in place to declare intent.
