* Move service tests to `client/network/tests` These tests depend on `sc-network` and `sc-network-sync` so they should live outside the crate. * Move some configs from `sc-network-common` to `sc-network` * Move `NetworkService` traits to `sc-network` * Move request-responses to `sc-network` * Remove more stuff * Remove rest of configs from `sc-network-common` to `sc-network` * Remove more stuff * Fix warnings * Update client/network/src/request_responses.rs Co-authored-by: Dmitry Markin <dmitry@markin.tech> * Fix cargo doc --------- Co-authored-by: Dmitry Markin <dmitry@markin.tech>
