      Cause: When an administrator set the `managementState` of the vSphere CSI driver operator to `Removed`, the cleanup process would delete an associated `PrometheusRules` custom resource. This resource incorrectly contained both vSphere-specific alerts and telemetry recording rules.
      Consequence: Important telemetry metrics related to vSphere storage were lost, impacting cluster health monitoring and reporting.
      Fix: The telemetry recording rules have been moved into a separate `PrometheusRules` object that is no longer tied to the lifecycle of the vSphere CSI driver operator.
      Result: Now, removing the vSphere CSI driver operator correctly deletes only the vSphere-specific alerts, while the essential telemetry metrics are preserved.

      This is a clone of issue OCPBUGS-62669. The following is the description of the original issue:
      —
      When the vSphere CSI driver operator is removed (using managementState: Removed), OCP removes vSphere problem detector PrometheusRules. This object contains alert definitions which should be removed (VPD should not alert if the driver is removed), but it also contains metrics that are transported via telemetry and we do want to keep these.
