Ansible 2.4+ suffers from a precedence bug when including tasks in
roles. It appears that a file in a relative tasks/ path inside the
current working directory is preferred over an identical file
from the role itself. For example:
task path: /home/zuul/.ansible/roles/previous_galera_server/tasks/galera_install.yml:20
included: /home/zuul/src/git.openstack.org/openstack/openstack-ansible-galera_server/tasks/galera_install_apt.yml for container1
As one can see, instead of including the galera_install_apt.yml from the
/home/zuul/.ansible/roles/previous_galera_server/tasks/ directory, the
one which is relative to the current working directory
(/home/zuul/src/git.openstack.org/openstack/openstack-ansible-galera_server/)
is preferred. We can simply workaround that by entering a different
directory which doesn't look like a role directory structure before executing
that part of the upgrade job.
