/**
* A request limiter which allows peeking ahead.
*
* This is valuable to reduce the cache backend load in scenarios
* like a login when we only want to consume a token on login failure,
* and where the majority of requests will be successful and thus not
* need to consume a token.
*
* This way we can peek ahead before allowing the request through, and
* only consume if the request failed (1 backend op). This is compared
* to always consuming and then resetting the limit if the request
* is successful (2 backend ops).
