`benchmark_local_k8s.sh` take these steps to measure `auto-pause` vs. `non auto-pause`. `benchmark_local_k8s.sh` take these steps to measure `auto-pause` vs. `non auto-pause`.
1. start each local kubernetes tool 1. start each local kubernetes tool
2. deploy sample application(nginx deployment) 2. deploy sample application(nginx deployment) to each tool
3. wait 1 minute without anything 3. wait 1 minute without anything

5. enable auto-pause addons(only if tool is minikube) 5. if tool is minikube, enable auto-pause addon which pause control plane
6. wait 3 minute without anything 6. if tool is minikube, wait 1 minute so that control plane will become Paused status(It takes 1 minute to become Pause status from Stopped status)
7. measure No.6 idle CPU usage with [cstat](https://github.com/tstromberg/cstat) 7. if tool is minikube, verify if minikube control plane is paused
8. if tool is minikube, wait 3 minute without anything
9. if tool is minikube, measure No.8 idle CPU usage with [cstat](https://github.com/tstromberg/cstat)
