Create discovery_ip_status.js

This script maps a list of IP addresses to their corresponding Discovery Status in ServiceNow. It checks each IP in the CMDB for a matching CI record, retrieves the related discovery status from the discovery_device_history table, and returns a structured list showing which discovery status each IP belongs to.
