podman kube play reads only the first entity in the configmap files passed with --configmap

[ygalblum]

Issue Description

When using podman kube play the caller may pass an additional file that includes config maps though the --configmap parameter. When this parameter is passed, podman reads and processes only the first entity in the file. However, a YAML file may include multiple sections. As a result, users cannot hold multiple configmaps in one file.

Steps to reproduce the issue

Steps to reproduce the issue

1. Create a configmap.yaml file with two configmap sections
2. Create a pod.yaml file in which the pod references the second configmap in the configmap.yaml file
3. Run podman kube play --configmap=./config-map.yaml pod.yaml

Describe the results you received

Error: cannot set env : configmap not found

Describe the results you expected

Podman should read the entire configmap file and extract all the entities inside it.
