Generate Kubernetes PersistentVolumeClaims from named volumes

Fixes #5788

This commit adds support for named volumes in podman-generate-kube.
Named volumes are output in the YAML as PersistentVolumeClaims.
To avoid naming conflicts, the volume name is suffixed with "-pvc".
This commit adds a corresponding suffix for host path mounts.
Host path volumes are suffixed with "-host".

 Ideally the input file would be one created by Podman (see podman-generate-kube(1)).  This would guarantee a smooth import and expected results.

+Only two volume types are supported by play kube, the *hostPath* and *persistentVolumeClaim* volume types. For the *hostPath* volume type, only the  *default (empty)*, *DirectoryOrCreate*, *Directory*, *FileOrCreate*, *File*, and *Socket* subtypes are supported. The *CharDevice* and *BlockDevice* subtypes are not supported. Podman interprets the value of *hostPath* *path* as a file path when it contains at least one forward slash, otherwise Podman treats the value as the name of a named volume. When using a *persistentVolumeClaim*, the value for *claimName* is the name for the Podman named volume.

 Note: If the `:latest` tag is used, Podman will attempt to pull the image from a registry. If the image was built locally with Podman or Buildah, it will have `localhost` as the domain, in that case, Podman will use the image from the local store even if it has the `:latest` tag.
