* Enhanced peer-ex protocol - added rate limiting, added response status and desc to the rpc * Better error result handling for PeerEx request, adjusted tests * Refactored RateLimit configuration option for better CLI UX - now possible to set separate limits per protocol. Adjusted mountings. Added and adjusted tests * Fix libwaku due to changes of error return type of fetchPeerExchangePeers * Fix rate limit setting tests due to changed defaults * Introduce new gauge to help dasboard effectively show current rate limit applied for protocol * Adjust timeing in filter rate limit test to let macos CI test run ok. * Address review findings, namings, error logs, removed left-overs * Changes to reflect latest spec agreement and changes. PeerExchange RPC is changed the now respond structure will contain status_code and status_desc.
