What ❔
Alternative to #3487
Before this PR EN based its gas pricing solely on main node's fee params which are based on immediate market conditions and not representative of the open batch's fee input. This is a problem on environments with long-running batches. This PR makes EN fetch main node's batch fee input along with fee params and report fetched batch fee input from its fee input provider.
