func Become(ctx context.Context) error

Become ensures that the current pod is the leader within its namespace. If run outside a cluster, it will skip leader election and return nil. It continuously tries to create a ConfigMap with the provided name and the current pod set as the owner reference. Only one can exist at a time with the same name, so the pod that successfully creates the ConfigMap is the leader. Upon termination of that pod, the garbage collector will delete the ConfigMap, enabling a different pod to become the leader.
