the registry EDEX. Added DATA_DELIVERY_ID to environment that is used instead
of site id for identification when participating in the federation
and subscription identification.
Amend: Created common data delivery package com.raytheon.uf.edex.datadelivery. Moved DataDeliveryIdUtil there.
Created ClusterIdUtil. DataDeliveryIdUtil uses that utility. It also verifies the id against the awips sites.
Changed centralRegistry.sh to set CLUSTER_ID to NCF.
Handle cases where site id is HAK or HUS.
Check for empty id setting in Cluster ID Util.
Return full id for Data Delivery ID.
Simplify Data Delivery ID and return Cluster ID.
