/**

* Before a given request containing a number of operations can proceed,
* RateLimiter determines doing so stays under the provided rate limits. It can
* also determine how much time is required before a request can be made.
*
* RateLimiter can also implement a gradually increasing rate limit. This is
* used to enforce the 500/50/5 rule
* (https://firebase.google.com/docs/firestore/best-practices#ramping_up_traffic).
