Aggregated Status

We would perhaps consider this a status like any other, just defined to indicate the overall status of all components. It would be linked to the main component. Eg:

<node>/status/system.aggregated

An option would also be to split each aggregated status part into topics: <node>/status/system.aggregated.high/main <node>/status/system.aggregated.low/main <node>/status/system.aggregated.local_mode/main
