Multi check page support

currently you can have multiple pages but each of them shows the same status and providers. It might be useful to have the option to create multiple pages with different providers/status infos.

This would allow better access control for different users or tools requesting the status. Also it would allow to group status based on their calculation impact, eg one page that only has core status info which can be polled often and which is easy to calculate. And then another page with more heavy calculations that can be checked after an installations, update or restore etc.
