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.
