defaultjson_ansible_callback

Extends Ansible default STDOUT callback to write json log file if ANSIBLE_JSON_LOG_FILE is set. Default output will still go to STDOUT
This is simply a merge of default.py and json.py from https://github.com/ansible/ansible/tree/devel/lib/ansible/plugins/callback

usage:

For single play usage, copy into callback_plugins folder relative to playbook and export environment variable

export ANSIBLE_STDOUT_CALLBACK=defaultjson
export ANSIBLE_JSON_LOG_FILE=test.log

To send JSON dump to STDOUT, export ANSIBLE_JSON_LOG_DEBUG e.g.

export ANSIBLE_JSON_LOG_DEBUG=true
