And include some node-specific configurations there with backwards compatibility. Note that in the future we'll remove Ledger's fields from the ProtocolConfiguration and it'll be possible to access them in Blockchain directly (not via .Ledger). The other option tried was using two configuration types separately, but that incurs more changes to the codebase, single structure that behaves almost like the old one is better for backwards compatibility. Fixes #2676.
