Remove:

* `NetworkStatusSinks`
* `NetworkStatus`
* `NetworkWorker::status()`
* `sc_service::SpawnTasksParams::network_status_sinks`
* `sc_service::Configuration::informant_output_format`

Also:
* `sc_service::build_network()` does not return `network_status_sinks`
* `sc_service::run()` and `sc_informant::build()` do not report `NetworkStatus` events (it was broken for some time)
