+=head3  getNodeDomains
+
+		Gets the network domain for a list of nodes
+
+		The domain value comes from the network definition 
+		associated with the node ip address.
+
+		If the network domain is not set then the default is to 
+		use the site.domain value
+
+    Arguments:
+       list of nodes
+    Returns: 
+		error - undef
+		success - hash ref of domains for each node
+    Globals:
+		$::VERBOSE
+    Error:
+    Example:
+     my $nodedomains = xCAT::NetworkUtils->getNodeDomains(\@nodes, $callback);
