Grouping-handler's type attribute does not support expressions

When creating messaging grouping in cluster mode it is necessary to provide <type> for <group-id> for each node. In a cluster there could only one node with group-id <type>LOCAL</type> and remaining nodes have to be of type REMOTE. In JBoss EAP 6 in domain cluster there is only one profile for each node so it is necessary to be able to specify type as an expression i.e <type>${type.name}</type>
