Description of problem:
when using localhost connection (other roles are working properly) manageiq roles not working due to using engine_fqdn instead of engine_url which is passed (in some form) from RHV Credentials

"msg": "The task includes an option with an undefined variable. The error was: 'engine_fqdn' is undefined\n\nThe error appears to have been in '/etc/ansible/roles/oVirt.manageiq/tasks/main.yml': line 3, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n- block:\n  - name: Login to oVirt engine\n    ^ here\n"

How reproducible:
always

Steps to Reproduce:
1. run manageiq role from Ansible Tower with localhost connection and specified RHV Credentials
