Test if ipactl starts services stopped by systemctl

This will first check if all services are running then it will stop
few service. After that it will restart all services and then check
the status and pid of services.It will also compare pid after ipactl
start and restart in case of start it will remain unchanged on the
other hand in case of restart it will change.
