add support for `ResourceUnavailable` p2p error (#3476) 
The `p2p-interface.md` spec defines a `ResourceUnavailable` error to
return in situations where data that exists on the network is locally
unavailable, e.g., when a block within `MIN_EPOCHS_FOR_BLOCK_REQUESTS`
is requested by `BeaconBlocksByRange` but cannot be provided. This patch
adds support for that additional error code.

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
