Other options - Could add an event as part of QueryAllCmd (prints name to replace CFE_ES_ListApplications), QuerryAllTasksCmd (prints task name/id, app name/id to replace CFE_ES_ListTasks).

Note CFE_ES_ListResources still seems unique/useful but it only does counts. Might make more sense to include names or possibly other info... or maybe would make even more sense to include resource counts in the housekeeping message? It's got counts for core apps, external apps, tasks, libs, why not resources? Or maybe just a by request packet (add new) that has all the counts? Send to a file doesn't really seem to have that much of a benefit.

Note - no strong opinions expressed, seems like approach in the comments above would be beneficial to users. Suggesting that as a path forward (events for the name/tasks as part of the already existing commands, new more informative output for resources).
