Divma 2063c0fa0d Initial work to remove engines fallback from the execution_layer crate (#3257) 
## Issue Addressed

Part of #3160 

## Proposed Changes
Use only the first url given in the execution engine, if more than one is provided log it.
This change only moves having multiple engines to one. The amount of code cleanup that can and should be done forward is not small and would interfere with ongoing PRs. I'm keeping the changes intentionally very very minimal.

## Additional Info

Future works:
- In [ `EngineError` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L173-L177)) the id is not needed since it now has no meaning.
- the [ `first_success_without_retry` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L348-L351)) function can return a single error.
- the [`first_success`](9c429d0764/beacon_node/execution_layer/src/engines.rs (L324)) function can return a single error.
- After the redundancy is removed for the builders, we can probably make the [ `EngineErrors` ](9c429d0764/beacon_node/execution_layer/src/lib.rs (L69)) carry a single error.
- Merge the [`Engines`](9c429d0764/beacon_node/execution_layer/src/engines.rs (L161-L165)) struct and [`Engine` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L62-L67))
- Fix the associated configurations and cli params. Not sure if both are done in https://github.com/sigp/lighthouse/pull/3214

In general I think those changes can be done incrementally and in individual pull requests.

Overview

Lighthouse is:

  • Ready for use on Ethereum consensus mainnet.
  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
  • Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
  • Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys, the Decentralization Foundation and private individuals.
  • Actively involved in the specification and security analysis of the Ethereum proof-of-stake consensus specification.

Staking Deposit Contract

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical staking deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse-blog.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.

Branches

Lighthouse maintains two permanent branches:

  • stable: Always points to the latest stable release.
    • This is ideal for most users.
  • unstable: Used for development, contains the latest PRs.
    • Developers should base their PRs on this branch.
