CLI output should be simplifed when running a command

When running a command like the following:
[domain@192.168.0.10:9999 /] /server-group=jb248-group:add(profile=ha,socket-binding-group=ha-sockets,socket-binding-port-offset=1000)
{
"outcome" => "success",
"result" => {
"domain-results" =>

,
"server-operations" => undefined
}
}

Showing anything more then success is problematic and showing those two lines of undefined is scary as it makes me think something did not work correctly. It would be nice if just a success message was posted.
