 PVCScale test creates first the number of Pods specified in `PVCSCALE_MAXPODS` variable. Once all Pods are in `READY` state with PVC in `Bound` status,  PVCScale test collects data for all Pods when they are started, and from this information we can then see how long it takes to start Pods from Pod1..PodN.
