[RDS] Add support for rolling resizing (scaling up/down) of DBInstance

[vishalkatikineni]

Is your feature request related to a problem?
Changing the instance size does in-place replacement which causes downtime if we apply the change across multiple DBInstances at the same time with in a cluster.

Describe the solution you'd like
If we can have life-cycle annotation for create-before-destroy that will help reduce the downtime.

Describe alternatives you've considered
We are changing the DBInstance size on one DBInstance at a time, and that is time consuming.

Hi @vishalkatikineni,
Thank you for raising this feature request!

ACK controllers are designed as declarative wrappers around AWS service APIs that provide a 1:1 mapping between Kubernetes resources and AWS resources. We focus on declarative state management rather than implementing custom deployment strategies or orchestration patterns beyond what AWS natively provides.

For complex orchestration scenarios like yours, check out Kro - it's purpose-built for orchestrating Kubernetes resources with custom workflows and sequencing. Kro could help you implement the sequential update pattern you need while leveraging ACK resources under the hood.

Thanks again for the feedback - it helps us understand how ACK is being used!
