Fix role relative variable resolution (#19)
Fix role relative variable resolution (#19)

- According to Ansible issue #18417
  (https://github.com/ansible/ansible/issues/18417)
  the variable resolution by a combination of "include_vars"
  and "with_first_found" resolves the file in the parent role
  first, which will likely lead to unexepected behaviour, if
  this role is included as a dependency and the parent role
  includes variable files with matching names.
