[S6100] Improve S6100 serial-getty monitor, wait and re-check when getty not running to avoid false alert.
#### Why I did it
On S6100, the serial-getty service some time can't auto-restart by systemd. So there is a monit unit to check serial-getty service status and restart it.
However, this monit will report false alert, because in most case when serial-getty not running, systemd can restart it successfully.
To avoid the false alert, improve the monitor to wait and re-check.
Steps to reproduce this issue:
1. User login to device via console, and keep the connection.
2. User login to device via SSH, check the serial-getty@ttyS1.service service, it's running.
3. Run 'monit reload' from SSH connection.
4. Check syslog 1 minutes later, there will be false alert: ' 'serial-getty' process is not running'
#### How I did it
Add check-getty.sh script to recheck again later when getty service not running.
And update monit unit to check serial-getty service status with this script to avoid false alert.
#### How to verify it
Pass all UT.
Manually check fixed code work correctly:
```
admin@***:~$ sudo systemctl stop serial-getty@ttyS1.service
admin@***:~$ sudo /usr/local/bin/check-getty.sh
admin@***:~$ echo $?
1
admin@***:~$ sudo systemctl status serial-getty@ttyS1.service

Why I did it
To gracefully unmount filesystems and stop containers while performing a cold reboot.
Unmount ONIE-BOOT if mounted during fast/soft/warm reboot
How I did it
Override systemd-reboot service to perform a cold reboot.
Unmount ONIE-BOOT if mounted using fast/soft/warm-reboot plugins.
How to verify it
On reboot, verify that the container stop and filesystem unmount services have completed execution before the platform reboot.
