Backport commits sonic-net#3492 and sonic-net#3203.
What I did
Add back the support to call reboot -f.
The support for this option was accidentally removed as part of this PR sonic-net#3203.
The same PR for 202311 doesn't have this mistake - sonic-net#3204.
Add the pre_reboot_hook script execution, add the watchdog arm before the reboot, in order to support the graceful reboot instead of the sysfs power cycle, to avoid filesystem corruption.
How I did it
Add back option -f for reboot script.
Modify the scripts/reboot.
How to verify it
Call reboot -f.
Start watching logs by using show log -f and journalctl -p debug -f.
Execute the reboot command from the switch CLI.
Check in logs that all systemd services terminated correctly.
