net-shapers: implement NL group operation

Browse source

Allow grouping multiple leaves shaper under the given root.
The node and the leaves shapers are created, if needed, otherwise
the existing shapers are re-linked as requested.

Try hard to pre-allocated the needed resources, to avoid non
trivial H/W configuration rollbacks in case of any failure.
