Running task or role before any playbooks
What you are looking for is the meta/main.yml in the roles of Ansible.

So make your every playbook (the ones you want to run after a task/role) as a role itself (to make it secondary execution) and what ever task/role you want to run before it should be added to the meta/main.yml of all the secondary execution roles. This would make all your roles execute the role mentioned in meta/main.yml
