This change added alarm 250.004, "IPsec certificates renewal failed".
This alarm will be raised by the ipsec-cert-renew cron job when the
renewal failed, and will be cleared when cron job script is re-run,
either manually or by cron, after the error is fixed.
Test Plan:
PASS: Simulate a failure condition (eg, ipsec-client return non zero),
run the cron job script, verify the IPsec renewal fails, and
alarm 250.004 is raised.
PASS: Run the script with IPsec cert not being about to expire, verify
the script finish successfully and alarm 250.004 is cleared.
