split up DefaultLogWriter::logRequest()

[lsmith77]

Would you be open a to a PR to split this method by extracting a protected method “getMessage()” that basically does everything except for the call to Log::info()? This would make it feasible to extend the class in case one wants to store the data else where, f.e. in a DB. Potentially there should even be another “formatMessage()” method and “getMessage()” just provides an array of data. what do you think?
