Why I did it
After this pull request sonic-net#18295 , the pmon has been added to the start list in fast/warm reboot scenarios. However, certain non-critical daemons of pmon could be delayed, resulting in a saving of approximately 1 second in the reboot process. For performance considerations, especially as the current time usage of fast reboot is closer to 30 seconds limitation, this change could ease the pressure.

How I did it
add a script as fast/warm reboot monitor and relative supervisord rlues.
once the script exited means the reboot process has ended, other delayed daemon would then initialize.
How to verify it
check the fast/warm reboot time usage
