Update include statements to newer syntax

[deadbok]

Ansible on Debian stretch has the following warning:

[DEPRECATION WARNING]: Specifying include variables at the top-level of the 
task is deprecated. Please see:

http://docs.ansible.com/ansible/playbooks_roles.html#task-include-files-and-
encouraging-reuse

 for currently supported syntax regarding included files and
 variables.
This feature will be removed in a future release. Deprecation 
warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

Description of the new syntax is here:

http://docs.ansible.com/ansible/latest/playbooks_reuse.html

The new syntax is supported in Ansible version 2.4+ according to this http://docs.ansible.com/ansible/latest/playbooks_reuse_includes.html.

Debian Jessie install version 1.7.2:

vagrant@jessie:~$ ansible --version
ansible 1.7.2

@moozer Do you need Jessie support?

It is the vars section of test.yml.

I have replaced it with stuff in group_vars/all.yml
