Handle task name interpolation

[louisquentinjoucla]

Hi everyone 👋 ,

With Ansible you are able to interpolate task name in certain circumstances.
One is when you use include_tasks, you are able to interpolate your tasks name in the included file like the following:

---

- name: "Echo {{ include_message }}"
  shell: "echo {{ include_message }}"

Unfortunately the task name is not yet interpolated in hook v2_runner_on_start for linear strategy, which cause B event to have a different name than the E event. As the E & B events name differs, the end is not catch, here is an example:

Fortunately v2_playbook_on_task_start hook (which is triggered before v2_runner_on_start) returns the interpolated name. We could use that.
