Overview

Package discovery is implements discovery interface for plugin discovery Discovery is the interface to fetch the list of available plugins, their supported versions and how to download them either stand-alone or scoped to a server. A separate interface for discovery helps to decouple discovery (which is usually tied to a server or user identity) from distribution (which can be shared).
