PHP-54 Update RateLimiter to match specs

Also added this as TODO to the agent. Wondering if it's worth refactoring a bit so we can have a isRateLimited($event) instead of doing it like this so we can re-use this logic in the agent.

I was thinking about this but profiles need to be removed from transaction and I didn't want to introduce mutation in the RateLimiter.
That said we should look into refactoring to use it in both places
