Retransmit code has moved to core/src/cluster_nodes.rs and has been
significantly revised.
gossip/tests/cluster_info.rs is testing the old code which is no longer
relevant.
https://github.com/solana-labs/solana/pull/27193
added hash domain to ping-pong protocol.
For backward compatibility responses both with and without domain were
generated and accepted.
Now that all clusters are upgraded, this commit enforces the hash domain
by removing the response without the domain.
In order to maintain backward compatibility, for now the responding node
will hash the token both with and without domain so that the other node
will accept the response regardless of its upgrade status.
Once the cluster has upgraded to the new code, we will remove the legacy
domain = false case.
