RHELPLAN-46757 - bug with current implementation of platform/version specific vars/tasks file include/import

[nhosoi]

tests/tasks/setup_test.yml is updated based on https://github.com/oasis-roles/meta_standards

• Using loop instead of with_first_found.

• Using '_' instead of '-' in the platform/version specific file name.

• Using absolute path for var lookup Note: since the include_var is used in the playbook, the absolute path starts with {{ playbook_dir }} instead of {{ role_path }}.

• Replacing "include:" with "include_tasks" in the test playbooks. See the notes in https://docs.ansible.com/ansible/latest/modules/include_module.html#notes regarding nonintuitive behavior and possible future deprecation.
