tool_list file loading

[bernt-matthias]

The tool list file located in the directory files is not loaded in ansible 2.2.

tasks/install_tool_list.yml

• name: get tool list
  include_vars: "{{ tool_list_file }}"

fatal: [bioinf-test]: FAILED! => {"ansible_facts": {}, "changed": false, "failed": true, "message": "Unable to find 'tool_list.yaml' in expected paths."}

If I place tool_list.yaml in a director vars it works.
