Add some success/error messages to 'cgred' service.

Add some success/error messages to 'cgred' service.

Hi,

The existing 'cgred' service displays a success message ([ OK ]) when
the service is starting, but it does not display any messages when it
is stopping/reloading. So this patch adds some success/error messages
to 'cgred' service like the following:

 # service cgred start
 Starting CGroup Rules Engine Daemon...
                                                            [  OK  ]
 #

 # service cgred stop
 Stopping CGroup Rules Engine Daemon...
                                                            [  OK  ]
 #

 # service cgred restart
 Stopping CGroup Rules Engine Daemon...
                                                            [  OK  ]
 Starting CGroup Rules Engine Daemon...
                                                            [  OK  ]
 #

 # service cgred reload
 Reloading rules configuration...
                                                            [  OK  ]
 #

This patch's purpose is almost same as the one of 'cgconfig' service:
