When upgrading from releases it could happen that you need to do some manual steps (i.e. upgrading from postgres 9.6 to 10). In these cases you'd want to check the docker-compose.yml and then launch it by yourself. Today we don't have any method to get just the files that will be used while installing via compose, without starting the containers. This commit adds a variable named "compose_start_containers" (true by default) that, if false, will make the playbook just generate the files in the compose directory and not start the containers.
