Add alerts on disk IOPS and CPU IOWAIT %

To help catch heavy disk workloads before they become problematic, it would be great to have alerts on: - disk IOPS percentage utilization for disks without burstable IOPS - burst credit utilization for disks with burstable IOPS - CPU IOWAIT %

    I am voting for this proposal because our team was impacted by a node health failure driven by high CPU IOWait, which we lacked the capability to proactively monitor.

    The central point I'd like to highlight is a core principle for observability: all metrics that are available for view on the cluster metrics dashboards should also be available for creating alarms.

    Being able to clearly see the CPU IOWait metric in the UI dashboards during a post-incident review, while being unable to set up an active alert to catch it beforehand, creates a significant blind spot. Ensuring strict parity between visible metrics and alertable metrics is crucial for teams to implement robust, proactive monitoring.
