title: ansible access list of dictionaries
body: <p>I'm trying to create a bunch of groups and members for a custom module using an external var file. All I need to do is to access a list of dictionaries in a list.
  I have tried many things but the closest I might have for now is:
  vars.yml:</p>
  
  <pre><code>groups_and_members:
    FIRST_GROUP:
      "memberx":
        octet: 1
        action: add
      "nostandardy":
        octet: 3
        action: add
      "memberz":
        octet: 5
        action: add
    OTHER_GROUP:
      "member1":
        octet: 7
        action: delete
      "unexpected":
        octet: 1
        action: add
  </code></pre>
  
  <p>task.yml:</p>
  
  <pre><code>  - name: "add members"
      mymodule:
        cmd: "{{ item.value.action }}"
        parameters:
          name: "{{ item.key }}"
          octet: "{{ item.value.octet }}"
      with_items: "{{ groups_and_members }}"
  </code></pre>
  
  <p>So the idea is to take from the list (groups_and_members).value(FIRST_GROUP in the first iteration). and use its members attribute in cmd. But because I don't know the name of the group nor the name of the member, I'm not sure how to access them. I will not know the name of the groups or the members beforehand. The dicts should be in a list, to not have to make a new task in case there's a new dict.
  How can I access the group, member and member attributes?
  I have tried with_dict, with_subelements etc. but can't seem to figure it out.</p>
