…fix stdout_callback

Now cli_facts.py callback plugin returns self._cliargs as ImmutableDict. This breaks stdout_callback option.

To test:

Set environment variable export ANSIBLE_STDOUT_CALLBACK=yaml and run a role with any debug task, i.e. - debug: msg="{{ vars }}"

Expected result:

TASK [clusterverse/create : debug] *****************************************************************************************
ok: [localhost] =>
  msg:
    _cloud_type: aws
    _region: eu-west-1
    ansible_check_mode: false
    ansible_connection: local
    ansible_dependent_role_names: []
    ansible_diff_mode: false
    ansible_facts: {}
    ansible_forks: 50

Current result:

TASK [clusterverse/create : debug] *****************************************************************************************
