max_counter_sets represents the number of different counter sets
exposed and makes the upper limit for the counter set id provided
to describe/create counter sets verbs i.e. counter set id must be
in range [0, max_counter_sets - 1].

Counter set id will be used with counter set object in downstream patches.
