+fixes:
+  - The name_lower field in network_data.yaml can be used to
+    define custom network names but the ServiceNetMap must be
+    updated with the new names in all places.  This change
+    adds a new field to network_data.yaml - service_net_map_replace,
+    that should be set to the original name_lower so that ServiceNetMap
+    will be automatically updated.
