feat(kube play): flag to specify resources (pods, secrets, volumes) labels

Feature request description

When creating a pod (podman pod create), a secret (podman secret create), a volume (podman create volume) we can specify a --label flag, this is very handy to add metadata to resources.

The podman kube play command create pods, secrets, volumes, and have an --annotation property, but pods, secrets and volume do not support annotation, as mentioned in https://github.com/containers/podman/issues/26448 the annotation documentation should be updated.

Suggest potential solution

Adding a --label flag, that will propagate to each resources created by the podman kube play command.

Have you considered any alternatives?
