/**

 * 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).
