…lience This commit introduces dynamic weight adjustment for RPC providers, improving failover and resilience by adapting to real-time provider health. Key changes include: - Introduced a `Health` module (`chain/ethereum/src/health.rs`) to monitor RPC provider latency, error rates, and consecutive failures. - Integrated health metrics into the RPC provider selection logic in `chain/ethereum/src/network.rs`. - Dynamically adjusts provider weights based on their health scores, ensuring traffic is steered away from underperforming endpoints. - Updated `node/src/network_setup.rs` to initialize and manage health checkers for Ethereum RPC adapters. - Added `tokio` dependency to `chain/ethereum/Cargo.toml` and `node/Cargo.toml` for asynchronous health checks. - Refactored test cases in `chain/ethereum/src/network.rs` to accommodate dynamic weighting. This enhancement builds upon the existing static weighted RPC steering, allowing for more adaptive and robust RPC management. Fixes #6126

This PR and #6126 seem to do the same thing. Which one of these two should I review? |

Can you combine the two into one PR? The base PR also needs to be rebased against latest Looking at the two PR's, the first one introduces a new way to configure weights for RPC providers, and the second one seems to make that obsolete by making decisions on dynamic rather than static data but doesn't remove the additional config. What is the interplay between them? If we are doing dynamic weight calculations, which I think is the right way to go, we should not make weights configurable that are mostly ignored. |

Summary
This PR introduces dynamic weight adjustment for RPC providers, improving failover and resilience by adapting to real-time provider health. The system now dynamically adjusts provider selection weights based on health metrics including latency, error rates, and consecutive failures.
This enhancement builds upon the static weighted RPC steering implemented in #6126, making the RPC management more adaptive and robust.
