removed NodeInfo and using NodeConf instead

This is a significant change in the undelying data model!

nodeDb, err := node.New()

will result in a structure which contains the on disk
values. Only

nodeDb.FindAllNodes() or nodeDb.GetNode(id) will give
the nodes with its merged in profiles.

+### Refactoring
+
+- removed NodeInfo completely. node.FindAllNodes() will now give back 
+  the list of nodes with its merged in profiles. Also there is now a
+  node.GetNode(id) command which will give back a node with its merged
+  in profiles. Changes to this structures will not be reflected to the 
+  database, but must nodeYaml.Nodes or nodeYaml.NodeProfiles
+
