OADP-6653: CloudStorage exponential backoff by removing RequeueAfter #1937
Conversation
The operator was repeatedly logging "Secret already exists, updating" and "Following standardized STS workflow, secret created successfully" even when the secret content hadn't changed. This was happening because the CloudStorage controller calls STSStandardizedFlow() on every reconciliation, which always attempted to create the secret first, then caught the AlreadyExists error and performed an update. Changed the approach to: - First check if the secret exists - Compare existing data with desired data - Only update when there are actual differences - Skip updates and avoid logging when content is identical - Changed CloudStorage controller to use Debug level and more accurate message when STS secret is available (not necessarily created) This eliminates unnecessary API calls to the Kubernetes cluster and reduces noise in the operator logs. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Description
This PR implements exponential backoff for the CloudStorage controller using Kubernetes-native libraries. The controller leverages controller-runtime's built-in workqueue backoff mechanism for automatic retries with increasing delays when bucket operations fail.
