So 5 years after the original version, it's time to give this callback
plugin some needed rework.
This PR includes:
- Reuse same logic for failed, unreachable or Async errors
- Add playbook and task information at the top (easier to find context)
- Improve the sections (ie. indented content)
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
