Local sim impovements (#4551) 
* Local sim impovements

* Added support for running Capella and EIP-4844 simulations
  by downloading the correct version of Geth.

* Added support for using Nimbus remote signer and Web3Signer.
  Use 2 out of 3 threshold signing configuration in the mainnet
  configuration and regular remote signing in the minimal one.

* The local testnet simulation can now use a payload builder.
  This is currently not activated in CI due to lack of automated
  procedures for installing third-party relays or builders.

  You are adviced to use mergemock for now, but for most realistic
  results, we can create a simple builder based on the nimbus-eth1
  codebase that will be able to propose transactions from the regular
  network mempool.

* Start the simulation from a merged state. This would allow us
  to start removing pre-merge functionality such as the gossip
  subsciption logic. The commit also removes the merge-forcing
  hack installed after the TTD removal.

* Consolidate all the tools used in the local simulation into a
  single `ncli_testnet` binary.

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
