Users can set limiters for switches (elements whose level > 0) in Fat-Tree.
Coordinates in Fat-tree are now characterized by: <level, id>, level 0
elements are the leaves (processing nodes).
Uniform limiter behavior in routes: src, destination and middle nodes.
Changes in tests:
1) cluster-multicpu: adjust timing due to new limiters.
2) flatifier tests must be adapted for these reasons:
- Changed callback to create limiters from XML. Radicals in XML are valid for leaves in the tree. Use internal ID instead.
- Changed order of links in the route from get_local_route of Fat-trees.
* @param id Internal identifier in the torus (for information)
* @return Limiter link

* 1) StarZone A: A-CPU-3 -> link-up-A-CPU-3 -> A-CPU-0
