How to tell if it is using dockerio (deprecated) or dockerng? about docker-formula

[cdarwin]

At the time of writing the compose-ng formula, we were relying on the dockerio salt modules/states. A bit confusing, I suppose… I will add this caveat to the documentation initially and try to update the formula when I get a chance.

Hi @davidcodesido @cdarwin
I have tested compose-ng recently and it used lxc-docker-1.6.2 until I figured out pillar data was the issue. I've raised two PR, #135 and #137 to improve the situation. More extensive examples in README and pillar.example of compose user case would still be nice.

This is actually yaml idiosyncrasy according to saltstack documentation:

To ensure the object becomes a string, it should be surrounded by quotes. More information here.

The `pillar.example' has updated examples wrapped in quotes.

  compose:
    registry-datastore:
      dvc: True
      # image: &registry_image 'docker.io/registry:latest'  {#Fedora #}
      image: &registry_image 'registry:latest'  {# ubuntu/suse #}

<cut>

 nginx-latest:
      #image: 'docker.io/nginx:latest'  {# Fedora #}
      image: 'nginx:latest'     {# ubuntu/suse #}

I have been caught by this issue in the past.
