Ethan Lynn 6bc753582b Set stack status to FAILED when engine is down
When stack is in status IN_PROGRESS and engine service went down,
the status of stack will forever remain in IN_PROGRESS. This patch
add a db apid to get engine_id from stacklock and try to reset the
stack status to FAILED when engine is back.
