do not disconnect on receiving canceled request (#3869) 
LC cancels concurrent requests if one peer sent a correct response and
waiting for other peers is no longer useful. On the server side this
resulted in a descore (-500) and a likely disconnect. The behaviour is
changed to match `UnexpectedEOF`, `PotentiallyExpectedEOF` handling that
return an error response without disconnecting from the peer.

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
