Based on https://docs.ansible.com/ansible/latest/reference_appendices/config.html
the default callback paths do not contain `_plugin`. Thus `~/.ansible/plugins/callback_plugins` and `/usr/share/ansible/plugins/plugin_type/action_plugins` are incorrect. Verified on 2.7.5 that by default `plugins/action` works and `plugins/action_plugins` does not.
