include domain_id when creating groups

as of the liberty release, keystone has emitted deprecation warnings
when groups were created without a domain id specified; keystone would
fall back to using the default domain specified in keystone.conf.

as of newton, this fallback is being removed in favor of always
specifying the domain id, and raising an exception if it is not present.
