Unless a plugin declares "Gerrit-ApiType: plugin" in its manifest, assume it is an extension and only make the gerrit-extension-api available to it through the ClassLoader. For non-plugins, do not make any Guice bindings available from the server. This further restricts what an extension can see and do with the system internals.
