Monitor specific namespaces for configmap/secret updates (#2598)

Browse Source 
We allow functions to refer to configmap/secrets. We are monitoring all namespaces for config maps and secrets and also allow cross-namespace references.
This fix monitors configmaps/secret updates in specific namespaces. Also, we ignore cross-namespace references for configmap/secret updates.
