Description
**Describe the problem**
When adding a node to a cluster, the p99.99 is still impacted when a node is brought online and added to a load balancer.
**To Reproduce**
Add a node to an existing cluster and observe various SQL metrics (e.g. `sql.conn.latency-p99` or `sql.service.latency-p99.99 metrics`).
