Fixes #10782 - global host status
Introduce new global host status that is composed of host substatuses.Each substatus defines a mapping to the global one which can result in
three values
Plugins can add their own substatuses. These are automatically
propagated also to API.
Thanks to Tomas Strachota who wrote the original code.
