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.		2022-06-22 14:27:16 +00:00
