Add tracking log intelligence to ELK

This uses the facility and priority of tracking logs in syslog to parse them as json into ELK.  It lets you do all the nice Kibana stuff like trending and such on specific tracking fields, etc in near real time.

Now I'm not an expert on this file, but this seems like absolute magic. Maybe the comment can explain why 142 is the magic number (why not just 42? :stuck_out_tongue_closed_eyes: )
