feat: [#932] replace mode core config option with private and `li…

…sted` flags

From:

```toml
[core]
mode = "public"
tracker_usage_statistics = true
inactive_peer_cleanup_interval = 600
```

To:

```toml
[core]
inactive_peer_cleanup_interval = 600
listed = false
private = false
tracker_usage_statistics = true
```
