+    Fix 2302: RO does not handle properly vnet IP ranges in Azure. 
+    OSM uses a specific vnet to create NS or VNF subnets when instantiating on
+    Azure. The vnets allow more than one address prefix, but RO only try to
+    allocate new subnets in the range defined in first place, ignoring the rest.
