This PR fixes two problems in devp2p tests (and through them, hive).
- Make the output more detailed about what is returned (always print packet kind).
- Allow Ping response to unsolicited findnode.
Without this PR, nethermind fails a hive protocol test, and I misinterpreted the result (NethermindEth/nethermind#3617). Ergo, the output was not fool-proof.
This PR modifies the post-PING-send expectations to both be laxer and stricter: it doesn't care what order the packets arrive, but also verifies that exactly one PING and one PONG is returned.
This PR fixes a false positive PONG 'to' endpoint mismatch seen in hive tests:
got {IP:172.17.0.7 UDP:44025 TCP:44025}, want {IP:172.17.0.7 UDP:44025 TCP:0}

This adds a test suite for discovery v4. The test suite is a port of the Hive suite for
discovery, and will replace the current suite on Hive soon-ish. The tests can be
run locally with this command:
devp2p discv4 test -remote enode//...
