Please add AWS Config Logs to this plugin

This is one of the key gaps between this and Splunk AWS app at the moment. Config log data follows the exact process as CloudTrail and I've gotten as far as launching a new input in Graylog that is correctly receiving notifications when new Config items arrive but obviously the data structure and elements are different between CloudTrail and Config so the plug in exceptions out when it sees fields that it doesn't have a variable for.
