+=head3  getNodesetStates
+       returns the nodeset state for the given nodes. The possible nodeset
+           states are: netboot, install, boot and discover.
+    Arguments:
+        nodes  --- a pointer to an array of nodes
+        states -- a pointer to a hash table. This hash will be filled by this
+             function.The key is the nodeset status and the value is a pointer
+             to an array of nodes.
+    Returns:
+       (return code, error message)
