Configuration options for Ironic driver (Bare Metal).
If using the Ironic driver following options must be set:
* auth_type
* auth_url
* project_name
* username
* password
* project_domain_id or project_domain_name
* user_domain_id or user_domain_name

Please note that if you are using Identity v2 API (deprecated),
you don't need to provide domain information, since domains are
a v3 concept.
