Aggregate and isolate statuses for customers within groups#1442

I would like to be able to share the status of groups on a status page, without showing each of the URLs being monitored.
Green, all monitors are OK
Orange, some are down
Red, all are down

I want to add a load of domain names hosted in different infrastructures, and then users can check if the whole system is down or just partially down - and we can also check internally the severity of an outage.

We would also like then for each website to have access to their own individual status. This way we do not share all the websites we have hosted within our organisation.
