- Fix the `cloudprovider_azure_api_request_duration_seconds` metric buckets to correctly capture the latency metrics. Previously, the majority of the calls would fall in the "+Inf" bucket.

- Metrics changes: Fix exposed buckets of `scheduler_volume_scheduling_duration_seconds_bucket` metric. ([#100720](https://github.com/kubernetes/kubernetes/pull/100720), [@dntosas](https://github.com/dntosas))
