feat(k8s): Add function to create job from cronjob

[steffsas]

Description

This PR introduces the functionality to create Kubernetes Jobs from an already applied CronJob. This function is similar to the command kubectl create job xyz --from=cronjob/xyz (see https://kubernetes.io/docs/reference/kubectl/generated/kubectl_create/kubectl_create_job/#synopsis). As the documentation of Kubernetes already implies, this functionality is mainly used for testing CronJobs, so it would perfectly align with terratest's mission.
