Michael,
You can't make up syntax and just have it automatically passed to the
modules, the original poster is asking about passing parameters repeatedly
to OpenStack.
Thomas,
To at least clean up your playbook, define a variable:
vars:
auth_url: "{{ lookup('env', 'OS_AUTH_URL') }}"
Etc. Then you don't need to repeat the unseemly lookup string each time.
