rename `PeerScoreXyzBlocks` -> `PeerScoreXyzValues` (#4318) 
The various `PeerScore` constants are used for both beacon blocks and
LC objects, and will likely also find use for EIP4844 blob sidecars.
Renaming them to use more generically applicable names not referring
to blocks explicitly aymore.

Networking

This folders hold a collection of modules to:

  • configure the Eth2 P2P network
  • discover, connect, and maintain quality Eth2 peers

Data received is handed other to the ../gossip_processing modules for validation.

Security concerns

  • Collusion: part of the peer selection must be kept random. This avoids peers bringing all their friends and colluding against a beacon node.
  • Denial-of-service: The beacon node must provide ways to handle burst of data that may come:
    • from malicious nodes trying to DOS us
    • from long periods of non-finality, creating lots of forks, attestations, forks
