Crate finality_relay

This crate has single entrypoint to run synchronization loop that is built around finality proofs, as opposed to headers synchronization loop, which is built around headers. The headers are still submitted to the target node, but are treated as auxiliary data as we are not trying to submit all source headers to the target node.
