WIP (DIO-911) Include job_id in ABS --json output

Prior to this commit, when using --service=abs and --json the job_id
value is not included in the JSON blob, which makes it difficult for
calling code to grab both the job_id and the hosts without text
processing the log messages printed to standard error.
