stats: Limit reporting by class id
This commit adds class_id fields to the rate_ctr and stat_item group
descriptions. The stats reporter code is extended to only process
groups whose class_id does not exceed a per reporter max_class level.
If the class_id is not set, the code assumes 'global' for groups with
idx == 0 and 'subscriber' otherwise.
The following vty command is added to config-stats:
level (global|peer|subscriber) Set the maximum group level
