* Libp2p protectors no longer needed, use PSK directly * Generate cluster 32-byte secret here (helper gone from pnet) * Switch to go-log/v2 in all places * DHT bootstrapping not needed. Adjust DHT options for tests. * Do not rely on dissappeared CidToDsKey and DsKeyToCid functions fro dshelp. * Disable QUIC (does not support private networks) * Fix tests: autodiscovery started working properly
