[RFE] Collect multiple screenshots of servers

Feature request;

We take screenshots once a minute anyway for the WebUI. Have the screenshots be saved for, say, 120 copies (two hours, but user configurable), after which they cycle off. This way, if a user wanted to be able to, they could scroll back on the screenshots in the browser.

This would also allow us to collect the screenshots in CI/CD to better debug build failures related to a server being online or not. For this reason, this is a post-beta tag enhancement, but one we'd like to have sooner than later.
