Add labels to a pod created via play kube

When using `podman play kube` with a YAML file that has pod labels,
apply those labels to the pods that podman makes.

For example, this Deployment spec has labels on a pod:

	apiVersion: apps/v1
	kind: Deployment
	metadata:
	  name: myapp
	  labels:
	    app: myapp
	spec:
	  selector:
	    matchLabels:
	      app: myapp
	  template:
	    metadata:
	      labels:
		app: myapp
	    spec:
	      containers:
	      - name: web
		image: nginx
		ports:
		- containerPort: 80

The pods that podman creates will have the label "app" set to "myapp" so
that these pods can be found with `podman pods ps --filter label=app`.
