Remove json formatter for job lifecycle

* We didn't really make use of json formatting across the app. Remove
  the special case json formatter. Instead, output all of the meta-data
  associated with a job lifecycle event every time. Before, we tried to
  only output this extra meta data when in DEBUG mode. It turns out this
  information is smaller than we thought and more useful than we thought
  so always output it.
