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
