Suppress CLI STDOUT for the service unless explicityly enabled

Signed-off-by: Graham Weldon [email protected]

Suppresses the CLI output unless explicitly enabled. When enabled (as it is now) large output can cause issues with other tools responsible for parsing /var/log/messages etc.

CLI output is likely to be useful only for debugging, and in production, reports should be JSON or directed to automate.
