Update: segment-io CM namespace from monitoring to application's

[zdtsw]

Description

From testing :

Changing this setting from the dashboard "cluster settings" page appears to work fine, but in the backend I see no changes to the odh-segment-key configmap.
configmap/secret from segment is now stored in the monitoring namespace instead of the applications namespace.
