As a user, I would like to have a special page which details all system status and notifications.

• move all system ping tests (proxies, compute resources, db response time etc) to this page
• provide a notification area in case the system detect failures of sort (e.g. something failed earlier, and identified as a configuration error etc, the error might be logged and acked on this page).
• provide a place to let the user some components are not configured (e.g. trend counters etc)
• allow plugins to extend as needed.
