fix: prevent seed peer address from being overwritten unless newer #4085

Description

  • Prevents seed peer addresses from being overwritten unless:
    • The seed peer signs a peer update after the node starts up,
    • directly connected to the seed peer.
  • Adds PeerValidator unit tests.

Motivation and Context

This is only a problem if the base node address has changed recently enough that it is not known to the rest of the network. The user has put the correct new address. The unsigned base node peer is added to the peer DB.

Soon after, the DHT syncs peers, since the previous address was signed, the base node peer is overwritten with the previous address.

How Has This Been Tested?

Unit test for PeerValidator tests this behaviour

Looks good to me
The code does some refactoring, the refactoring makes it easier to read to code.
Tested and works.

It failing this integration test however When a new node joins the network, it should receive all peers
