Feat/new dashboard screenshots

Created by: garloff

Two recent screenshots from gx-scs. I use them to explain how to read the dashboards and also explain what is observed there, including the explanation of a compute host with networking trouble.

@maliblatt, @frosty-geek - this exposes some real data from a PS owned test environment. I feel that this does not expose anything sensitive -- rather explain one case that has been observed and addressed successfully. But feel free to object to this PR.
