columnstoreSupport on a non-root install has systemctl msg printing to the screen

Initially reported by a customer and reproduced by support

The columnstoreSupport script is making 'systemctl' calls. And when its run as a non-root user, messages are printed to the screen.
1. So maybe filter out the messages from being printed as an option
2. Code make sudo a requirement, but best not do that. Some customers will not like that requirement.
