When the OSA connection plugin is used on older ansible versions,
and when haproxy runs in a container, a bug exists where the loop_var
fails to properly delegate the task to the haproxy container.
We can avoid using loop_var in the delegation of the task by simply
moving the loop_var up one level so that the endpoint-manage task
file can use {{ item }}.
This was introduced in the commit:
