A self-contained kind-cluster setup that measures the spiffe-csi-driver's
peak memory under a worst-case scale-up burst. The scenario: a long-running
cluster suddenly schedules N CSI-using pods, kubelet drives the resulting
mount churn against the existing driver process, and the driver's peak
resident-set size grows accordingly.
The driver does not need a SPIRE control plane to exhibit this behaviour: the
allocation pattern lives entirely in pkg/mount/isMountPoint. The dummy
