ntp service on centos is ntp.service, but cloud-init uses nptd.service

[Scott Moser]

The ntp (client) service file installed by the centos 7 'ntp' package is named
'ntpd' (note the d), but cloud-init's cc_ntp module identifies that
'service_name' as 'ntp'.

See below on centos 7. For centos 8, there is no 'ntp' package that I see,
it seems to have been replaced by chrony.

[root@cent71 ~]# rpm -ql ntp | grep systemd
/usr/lib/systemd/ntp-units.d/60-ntpd.list
/usr/lib/systemd/system/ntpd.service
[root@cent71 ~]# systemctl status ntp.service
Unit ntp.service could not be found.
[root@cent71 ~]# systemctl cat ntp.service
No files found for ntp.service.

This bug is believed to be fixed in cloud-init in version 20.4. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
