"""
Inject a pod kill fault targeting specified microservices by label in the configured namespace.

Note: This uses 'pod-failure' action instead of 'pod-kill' to prevent Kubernetes from immediately
recreating the pod. The 'pod-kill' action forcefully deletes pods, causing Kubernetes controllers
(Deployment/ReplicaSet) to immediately recreate them. The 'pod-failure' action makes pods unavailable
for the specified duration without deletion, allowing proper fault injection testing.

Args:
microservices (List[str]): A list of microservices labels to target for the pod kill experiment.
