Support for multiple kubernetes objects in `podman_kube_specs` `kube_file_content`

This role doesn't allow multiple objects in `kube_file_content` within `podman_kube_specs`.  `podman kube play` of recent podman on the other hand supports multiple objects for Pod, Deployment, PersistentVolumeClaim, ConfigMap, Secret and DaemonSet. Are there any plans for enabling this? 

I think I could contribute if that is something worth to introduce.
