ganglia - make codfw use ganglia_new::monitor

adjust the if-statement so codfw is treated like esams,
and uses the newer ganglia setup, with ganglia_new::monitor

Then we should be able to add "standard" back to install2001
and not run into a duplicate definition, while being an aggreagator
and also a client.  Per talk with Mark.
