Remove OpQueryNodeData and LUQueryNodeData

Now that LUQueryNodes supports all the functionality of LUQueryNodeData,
let's migrate gnt-node.ShowNodeConfig to use it and remove all traces of
OpQueryNodeData and LUQueryNodeData.

Change LUQueryNodes to return raw values and support selective listing

LUQueryNodes it's very similar to LUQueryNodeData, but it lacks two
