Hi @anndono. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Pull request overview

This PR migrates the codebase from using klog directly to contextual logging through the pkg/log package. This is a cherry-pick of multiple logging migration changes (#9664, #9707, #9773, #9778) to the release-1.34 branch. The migration standardizes logging by replacing a mix of plaintext and structured logging with consistent contextual logging, improving clarity and observability across the codebase.

Key changes:

• Import statements changed from k8s.io/klog/v2 to sigs.k8s.io/cloud-provider-azure/pkg/log
• Logger initialization using log.Background().WithName(...) or log.FromContextOrBackground(ctx).WithName(...)
• Structured logging with key-value pairs instead of formatted strings
