Pod chaos scenarios

Following are the components of Kubernetes/OpenShift for which a basic chaos scenario config exists today. Adding a new pod based scenario is as simple as adding a new config under scenarios directory and defining it in the config. For example, for adding a pod level scenario for a custom application, refer to the sample scenario provided in the scenarios directory (scenarios/customapp_pod.yaml).
