Currently, there is no way to get the network data for the HTTP calls done by the HTTP transports (which makes debugging harder). For SMTP, we do have the network data, but as logs (each SMTP command/response is its own log line which means that the logs are "polluted" and the data is not tied with the sent message).
This pull request adds a `getDebug()` method on `SentMessage`. That allows to get the debug data conveniently in a standardized way (for both SMTP and HTTP transports). I have moved the SMTP logs to this new mechanism and added support for HTTP transports.
