This change allows this playbook to be run using an older version of
ansible. This change is necessary for my use case where I am running all
OSA and related playbooks in a docker container locally for a Newton
deploy.
The use of Newton OSA's ansible bootstrap script means that the
openstack-ansible my workflow uses requires Ansible 2.1, which does not
support `include_tasks`. This change addresses that problem by replacing
`include_tasks` in the playbook that needs to be run using
openstack-ansible with `include` which produces the desired result.
