pre-task attribute error

[iacopo carraro]

Hello there,

i'm trying to include a yml file as a pre-task in my playbook. The problem is i can't pass custom parameters to it.

Here is my code:

```

pre_tasks:

    - { include: includes/notifications-start.yml, msg: my-msg }

```

`my-message` is a simple string, not a variable and also `msg` is not used in any other place.

Here is the error i see when i run the playbook:

```

$ ansible-playbook -i hosts/staginghosts web_deploy.yml

ERROR! 'msg' is not a valid attribute for a Task

The error appears to have been in '/path/to/my/repo/ansible/web_deploy.yml': line 9, column 7, but may

be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  pre_tasks:

    - { include: includes/notifications-start.yml, msg: my-task-name }

      ^ here
```

It appears that i can't add any custom variable name there.

Ansible version:

```

$ ansible --version
