The ability to update/refund the value of token bucket directly from user code

[androxylo]

The functionality I cannot find, please excuse if am wrong.

Suppose I execute a request for which I don't have a good way to estimate its cost in advance. After the request is done, I know its real cost more precisely. Then I can take the difference between initial cost estimate and real cost end refund/penalize the token bucket from the resulting cost.

Another case is when the backend has free resources or severely overloaded. I may want to accelerate or slowdown the token drip in all buckets. It could be done if I have an ability to change the current value one way or another.
