/system/processes/process/[pid]/args definition as leaflist does not make sense

[peterfeifanchen]

The definition asks for the command line arguments to be broken down into its components and added to args as leaflists. However, this seems unnecessarily complicated as how the arguments are typed out is dependent on the application. Openconfig spec shouldn't be asking for mappings that have to guess which arguments form a set and which are independent.

If instead this meant that the leaflist should be a list of arguments delimited by spaces, then it would collide with the uniqueness requirement for leaflist leafs since there is no way to guarantee that same argument + value won't show up twice in this case.

It would be much simpler if this was just a string, I feel rather than a leaf list.
