Custom increments for RateLimiter

[khepin]

👋 Trying to gauge if there would be interest in a feature to allow incrementing the "attempts" by a custom amount on the RateLimiter. Currently only the hit method is directly available which will increment by 1.

context

We did something similar for queue workers (by extending the base RateLimiter class) where we implemented a job middleware that grabs a tenant id for the job and times the time it took to execute the job in milliseconds. We increment the rate limit by the number of milliseconds spent and for any given tenant ID that's over a given limit, we re-queue the job on a separate queue.

This helps guarantee that the main queue is processing fast for all tenants and tenants that create too much work and are clogging the queue get moved to a separate queue where the work they created can be processed at a slower rate.

Since a job might take 300ms, we need a way to increment the rate limiting value by that amount directly.

implementation

I'm happy to contribute an implementation if there's interest in the feature.
