The auth parameters `admin_username`, `admin_password`,
`admin_tenant_name` and `admin_url` of the [ironic] config
option group are now deprecated and will be removed in a
future release. Using these parameters will log a warning.
Please use `username`, `password`, `project_name `and
`auth_url` instead.
