Make colored ball "System health status" explicit

We currently display a green/red colored ball to show system health status in the system page.

We got some community feedback regarding this colored ball. One user reported that he was confused about it: "Does this colored ball mean everything is ok or does it show up when something is not ok?"

We also need to take in consideration that relying on color only to show system health status can be a challenge for colorblind users.

Solutions: 
instead of icons, use the text "Yes/No" or "true/false", check which make sense for all fields
