Capacity Management: Debugging Exceeded Rate Limits

Sentry has improved its rate limiting mechanism by providing a "Snuba Customer Dashboard" for aggregate query overview, Sentry Trace View page for detailed query analysis, "warning zones" before rejecting queries, and organized information about throttled and rejected queries on Sentry. These improvements aim to reduce the time it takes to resolve customer support requests, provide better debugging information, and enable Sentry engineers to debug faster. The changes benefit Sentry users by allowing them to send queries to Snuba without changing their workflow, and providing detailed insights into rate limiting issues, including suggested actions for resolution.
