CPU and RAM info for Desktop Sessions

[brianmajor]

Although the reported in-use and requested CPU and RAM information show for Desktop sessions is correct, it is not useful because it is only a shell for displaying the containers launched from within the desktop. It could be misleading to users who are not aware of this architectural concept.

Ideally, one would have the ability to find these associated containers and report their usage instead.

I'm not suggesting any action on this at the moment, just recording the issue so we have a place to discuss options.
