Create vars/all_sn.yml to reduce redundancy

[lemoer]

There are a lot of variables, that are shared between all supernodes. We should outsource them into an own file vars/all_sn.yml

[lemoer]

- dns_recursive_allowed_private_rdns_zones:
  - "8.0.0.0.e.e.f.f.a.c.d.f.ip6.arpa."

from vars/all_hosts.yml should be migrated to there as well.

[lemoer]

Maybe we could use another level of abstaction with include:

supernode.yml:

---

- hosts: sn01
  tasks:
  - name: foo und bar
    set_fact:
      a:
        c: ['foo', 'bar']

  - name: print
    debug: var=a

  - include: add_it.yml b="hey"

  - include: add_it.yml b="hey"

  - name: print
    debug: var=a

add_it.yml:

--- 
- name: add it
  set_fact:
    a: "{{ a|combine({ \"c\": a[\"c\"] + [b] }) }}"

This include snippet adds variable b into array in a["c"].

output:

    },

            "bar", 
            "hey", 
            "hey"
        ]
    }, 
    "changed": false
}

Can you add a tangible example please? ;-)

And everybody is complaining about Perl regexes.
