Proposal with_all_found loop

Hi list,

I'd like to discuss a proposal for a loop with_all_found.
We have with_first_found, so implementation should be quite easy.

Target:

- name: Include OS specific variables
  with_all_found:
    - "{{ ansible_os_family }}.yml"
    - "{{ ansible_distribution }}.yml"
    - "{{ ansible_distribution }}-{{ ansible_distribution_major_version }}.yml"
  include_vars: "{{ item }}"

vars/Debian.yml:
pkg_list:
  - foo
  - bar
  - foobar
pkg_state: installed
service_management: systemd

vars/Ubuntu.yml
service_management: upstart

vars/Ubuntu-15.yml
service_management: systemd
ubuntu_15_specific_var: value

Result, running on Ubuntu 14.

pkg_list:
  - foo
  - bar
  - foobar
pkg_state: installed
service_management: upstart

Running on Ubuntu-15:
pkg_list:
  - foo
  - bar
  - foobar
pkg_state: installed
service_management: systemd
ubuntu_15_specific_var: value

Running on Debian:
see vars/Debian.yml

This might spare one task compared to what I'm doing right now and will
ease to override variables for specific versions/distributions.

- name: Include OS family specific vars
  include_vars: "{{ ansible_os_family }}.yml"

- name: Include distribution specific vars
  with_first_found:
    - "{{ ansible_distribution }}-{{ ansible_distribution_major_version }}.yml"
    - "{{ ansible_distribution }}.yml"
  include_vars: "{{ item }}"

What do you think?

Hey,

sure. I was more focused on the use case in Ansible Yaml.
