      "Classify tables and sessions contain relative node indexes. Management agent like Honeycomb,
       needs to use node names instead (indexes might change after vpp restart).
       VPP does not provide relative index to node name conversion (https://jira.fd.io/browse/VPP-219),
       also finding base node that is needed to perform the conversion
       is not allways possible (https://jira.fd.io/browse/VPP-220).

       Therefore Honeycomb needs to provide relative node to index mapping.";
