Add `Router` to the reputation server. `Router` is called on every incoming request and inits `Writer` that sends `Trust`s to the next route point or handle(logs in that implementation) them if current node is the end point of the route. Rename `onlyKeyRemoteServerInfo` struct for container to separate it from the same implementation of the same `ServerInfo` interface for reputation. Signed-off-by: Pavel Karpy <carpawell@nspcc.ru>
