Add "podman kube generate" command

"podman kube generate" creates Kubernetes YAML from Podman containers,
pods or volumes. Users will still be able to use "podman generate
kube" as an alias of "kube generate".

 **podman kube play** will read in a structured file of Kubernetes YAML.  It will then recreate the containers, pods or volumes described in the YAML.  Containers within a pod are then started and the ID of the new Pod or the name of the new Volume is output. If the yaml file is specified as "-" then `podman kube play` will read the YAML file from stdin.
 Using the `--down` command line option, it is also capable of tearing down the pods created by a previous run of `podman kube play`.
