Ctrl: add rate counter group introspection
Before user have to know group name and index in advance to request rate
counter value. Introduce introspection function which allows user to
obtain all the groups and their indexes by requesting 'rate_ctr.*'
variable.
This simplifies KPI dumping over ctrl interface.
