What

• When the app be unbinding of the service the config map should be removed
• if the CR is deleted, then the associating Config Map in the Mobile App namespace should be removed.

PS.: From what I said above, the configmap should be removed, but it is not necessarily the operator's job. If the configmap's parent object is setup correctly, you can use cascading deletion feature from k8s to delete the object automatically when the CR is deleted.
