This controller queries addresses of all the interfaces in the system
and presents them as resources. The idea is that can be a source for
many decisions - e.g. whether network is ready (physical interface has
scope global address assigned).
This is also good for debugging purposes.
Examples:
```
$ talosctl -n 172.20.0.2 get addresses
