VPS/VDS are not actual server they are are virtual thingy, so you cannot shutdown it using shutdown command. You can reboot the vps or kill vps from host server only using CP. So when you type shutdown command it will just kill all running services and restart everything again.
Most of these services needed to run different apps. You can disable following services as those are not used by VPS:
auditd
kudzu
rdisc
dc_server
lm_sensors
smartd
cpuspeed
irqbalance
microcode_ctl
Use ntsysv to disable above services. Mostly they may be in disabled state.
If you use Plesk/Cpanel then don't play much at OS level it will break something somewhere. If it is a plain VPS then you can modify services.
