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".
