[Addresses #49798515]Add JobStatus tracking to BatchResponse

What:
- Added a new model (JobStatus)
- Added parsing for reading values into an array of JobStatuses to
BatchResponse.
- Wrote a quick rake task to parse/see the statuses

Notes:  These job statuses are harder to detect because they aren't
instantly available when you submit the job.  It was necessary to wait for
a couple of minutes for the call to status to return this information.
BatchResponse conditionally parses this information if it is present.
