*Background:*
This caused due to centos 7 using systemd by default and switched to use of
{{systemctl}} command instead of {{service}}. Since that, service command exist
only in backward compatibility context and r optional. Currently optional
package, which provides this package called {{initscripts}}
Currently, everything ok r with standalone centos 7 image and it includes this
package installed by default. However docker image centos/centos:7 doesn't
provide this package by default, and systemd enabled image
centos/systemd:latest use {{systemctl}} without installed {{initscripts}}:
https://github.com/CentOS/sig-cloud-instance-images/issues/28
*Summary:*
Due to {{service}} command going to be deprecated, we need consider to switch
fully to {{systemctl}} replacement for systemd enabled images
