Change backoff policy for Abandoned Job failures

Jobs that are abandoned due to a certain number of
STOP_REASON_TIMEOUT_ABANDONED stop reasons will be rescheduled with an
exponential backoff policy. This is because these jobs are likely to be
empty and not perform any related work until the system times out the
job.
