+ * 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).
