<!-- PR description-->
Create a sliding window rate limiter which provides 2 guarantees:
1. Ensures we stay within service limits for a given window duration.
2. Allows token tracking and window sliding at a finer resolution. This allows for more accuracy at the cost of more frequent sliding & more memory usage.
This implementation is partially inspired by the centralized token grant mechanism in https://github.com/reugn/equalizer#slider.
