The problem is that when one_vip is used to contact the Leader delegate_to does not know which ansible_user should be used for the SSH connection, so it takes whatever it finds in hostvars.

To Reproduce

1. Define "global" ansible_user in the inventory.
2. Override ansible_user (different value) for all Front-ends (HA).
3. Run ansible-playbook.

Expected behavior
No error, delegate_to uses the correct SSH user.
