Hi Federico,

I'm currently looking into getting the f-interop CI tests, and I found that they are currently failing on the inclusion of the coap_testing_tool deployment.

Instead of executing the ansible-playbook executable directly, I think a better solution is to start the playbook with a simple "include"-statement. This has several advantages, like the easy definition of variables.

This means that we can then use the following statement in roles/coap/tasks/coap.yml in the f-interop repo:

- name: Run the provisionning
  include: "{{ finterop_proj_path }}/coap_testing_tool/ansible/main.yml"
  vars:
    - testing_tool_dir: "{{ finterop_proj_path }}/coap_testing_tool"

Instead of:

- name: Run the provisionning
  tags: coap
  become: True
  command: 'ansible-playbook {{ finterop_proj_path }}/coap_testing_tool/ansible/main.yml -i "localhost," --connection=local'

Can you accept this merge request, so that I can further debug the CI script?
