Use project_domain_id only in password auth

The method being changed constructs domain-related parameters that will
further be passed to the auth plugin. If project domain is not
passed, the method sets it to the default domain.

token_endpoint does not expect any information about domain,
because it uses only a token and URL. Passing it to auth plugin causes
an exception.

Construct domain-related parameters only for specific plugins, such
as password or totp.
