Title: dynamically detect tracker plugins and cache them instead of using config

refs #6065

FYI: A plugin now has to listen to any `Tracker` or `Request.initAuthenticationObject` event or it has to define dimensions in order to be detected as a tracker plugin. Before it was possible to add it manually to the PluginsTracker list in config which is no longer the case.
