this is the first pass at implementing init containers for podman pods. init containersare made popular by k8s as a way to run setup for pods before the pods standard containers run. unlike k8s, we support two styles of init containers: always and oneshot. always means the container stays in the pod and starts whenever a pod is started. this does not apply to pods restarting. oneshot means the container runs onetime when the pod starts and then is removed.
