Having a "policy" field in res_counter seems like it might be reusable
as something for other non-ratelimited res_counters. And even if it's
not, the memory overhead of a couple of extra fields in a res_counter
is trivial compared to the overhead of resource isolation anyway.

So my first approach to this would be just extend res_counter, and
then split them apart later if it turns out that they really do need
mutually incompatible code/handlers.
