Add test steps for automount with multi images

These test steps check the automount feature with multi images for
following item:
  1. multi images can be auotmounted with yaml file.
  2. if there are same path exist in the images, the last one
should trumps.
  3. the volume is mounted readonly in the container.
  4. the volumes are only mounted in the specific container, but
not the whole pods.
