Until the plugin is actually configured, it does not have access to the 
attributes - this is the same for external and built-in plugins.  For 
operations that just return information, such as getconfignames and 
getinfo, the plugin does not need to be configured.  For actions that 
actually DO something, like gethosts, status, reset, etc. the plugin 
does need to be configured.  Now if your plugin is loaded and 
configured, then even the getconfignames operation will have access to 
the attributes - but there is no reason to call getconfignames at this 
point because it was called before the plugin was loaded in order to see 
what attributes the plugin needs to be loaded.
