    Correct the inventory generation

    The missing quotes didn't trigger anything since "vars" is representing
    the vars() method...
    Adding the missing quotes allows to actually get the injected host
    variables in the inventory, among them the well needed "container_cli"
    for the validations.

    This patch also makes a huge update in the different inline dict, in
    order to make them more human readable. This should help for further
    editions.
