Updated schedule() to support job.info() lst rtype

Updated scheduler.schedule() to support new list return type for
job.info().

Earlier schedule() was overwriting the job_obj for passing the new
scale request to update_quota(). Its been replaced by new_req_obj to
differentiate the request objects.
