If the auth plugin is "Password", a project, username and password are needed to identify the user.
An optional domain may also be included. This is the most common type and is the default any time a username is supplied.
An auth URL for the Identity service is also required.
[Required: --os-auth-url, --os-project-name, --os-username; Optional: --os-password]
