phase1 jobs failing with undefined variables

[Rafael Folco]

These vars are undefined when calling the new collect-logs role from https://github.com/openstack/ansible-role-collect-logs:
  - artcl_collect_dir
  - working_dir
  - undercloud_user

This may be related to the collect-logs transition to an independent role (from tqe).
