ci(.travis.yml): update Ansible to 2.5.15

Additional changes have been made:

1) remove get_md5 parameter from stat module.  From
   https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.5.html#noteworthy-module-changes
   %
   The stat and win_stat modules have changed the default of the option get_md5 from true to false.
   This option will be removed starting with Ansible version 2.9
   %

2) rewrite the way we pass variables to roles. Use "vars" parameter for for that.  Inspired by
   https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.5.html#fixed-handling-of-keywords-and-inline-variables

3) migrate "with_items" to "loop" as this is "the recommended way to perform loops". Details:
   https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.5.html#migrating-from-with-x-to-loop
