Code Review
This pull request introduces a MaxScaleUpPercentage configuration to cap the number of connections added during a scale-up event for the dynamic channel pool. However, the current implementation has a logic flaw where it fails to scale up if the connection pool size reaches zero, which could lead to a permanent denial of service in certain recovery scenarios. Additionally, there are minor issues with comment formatting and the handling of a zero value for the new configuration, which could cause unexpected behavior for users attempting to disable scale-up.
