## Issue Addressed N/A ## Proposed Changes With https://github.com/sigp/lighthouse/pull/3214 we made it such that you can either have 1 auth endpoint or multiple non auth endpoints. Now that we are post merge on all networks (testnets and mainnet), we cannot progress a chain without a dedicated auth execution layer connection so there is no point in having a non-auth eth1-endpoint for syncing deposit cache. This code removes all fallback related code in the eth1 service. We still keep the single non-auth endpoint since it's useful for testing. ## Additional Info This removes all eth1 fallback related metrics that were relevant for the monitoring service, so we might need to change the api upstream.
