configured-rate-limiter

This is a wrapper around node-rate-limiter-flexible to work in the @gasbuddy/service opinionated service framework which uses Redis for other things. While the primary use is inside our Ambassador based external-auth service, it is useful to use the module in clients directly so that you can take advantage of in-process caching for blocked users and to avoid unnecessary network traffic when a simple front-end rate limiter isn't enough.
