Track and display the current network configuration (#1158)

Trello:
https://trello.com/c/KYDDRo30/3630-8-display-the-running-network-configuration

This PR adds support for tracking the status of the network devices and
displaying that information through the web UI.

## Extending the networking model

Now the `Device` struct includes information about [its current
state](https://github.com/openSUSE/agama/blob/<a class=hub.com/openSUSE/agama/commit/<a class="double-link" href="https://git"><a class=hub.com/openSUSE/agama/commit/d5f7da8d4b9f673f08348af6c7582cd65b414019">d5f7da8d4/rust/agama-server/src/network/model.rs#L465-L468),
including its IP configuration, MAC address, device state, etc.

To keep this information up-to-date, we introduced the concept of
[network
watchers](https://github.com/openSUSE/agama/blob/d5f7da8d4b9f673f08348af6c7582cd65b414019/rust/agama-server/src/network/adapter.rs#L38)
which listens for events in the corresponding backend and update the
network model accordingly. We implemented a [NetworkManager
Watcher](https://github.com/openSUSE/agama/blob/d5f7da8d4b9f673f08348af6c7582cd65b414019/rust/agama-server/src/network/nm/watcher.rs).

```

## Adapting the UI

When it comes to the web UI, we decided to make it work with the new
updates mechanism, but nothing else. We plan to invest some time in
rethinking that part of the UI (as we did for storge), but not now.
