## Issue Addressed Resolves #2278 ## Proposed Changes Implements the networking components for the Altair hard fork https://github.com/ethereum/eth2.0-specs/blob/dev/specs/altair/p2p-interface.md ## Additional Info This PR acts as the base branch for networking changes and tracks https://github.com/sigp/lighthouse/pull/2279 . Changes to gossip, rpc and discovery can be separate PRs to be merged here for ease of review. Co-authored-by: realbigsean <seananderson33@gmail.com>
