support foldersFromFilesStructure

[copolycube]

https://grafana.com/docs/grafana/latest/administration/provisioning/#dashboards indicate that we can push a structure of dashboards to grafana, but no options in the playbook allows this currently

workaround : for a dashboards/ directory at the same level of the playbook :

---
- name: Monitoring collector - grafana setup
  hosts: label_monitoring_server
  vars:
    become_user: root
    become: true
    dashboards_dir: /var/lib/grafana/dashboards-git
  roles:
    # # Using grafana collection

    - role: grafana.grafana.grafana
      vars:
