Separate Rate Limits for Transactions and Errors

### Problem Statement

**Separate Rate Limits for Transactions and Errors**

We would like the ability to set distinct rate limits for transactions and errors. Our goal is to allow errors to flow seamlessly, while imposing stricter rate limits on transactions. Currently, rate limits are applied per DSN, which limits flexibility. Although we recognize that a sampling rate for transactions exists, it is not always feasible to adjust it through code, especially in cases where a complex rollout process is required. Therefore, our request is for a feature that enables separate rate limits specifically for transactions and errors.
