previously in run_app_paas.sh, we captured stdout from the app and piped that into the log file. However, this came up with a bunch of problems, mainly: * exceptions with stack traces often weren't formatted properly, and kibana could not parse them * celery logs were duplicated - we'd collect both the json logs and the human readable stdout logs. instead, with the updated utils library, we can use that to log json straight to the appropriate directory directly.
