> v8 change:
> - change command defintion for leaf and nonleaf nodes (mulitple shared
> shapers can be specified)
> - pre-allocate memory for shared shaper ids array in nonleaf and leaf
> node add cli.
> - change clean_on_fail to string type in hierarchy commit cli
>
> v7 change:
> - fix the help info on leaf node add
>
> v5 change:
> - add shaper related parameters to leaf node add command
>
> v4 change:
> - remove softnic specific checks to make it generic for the devices
