Cinder and cinderclient assumes an attachment create request will always contain instance_uuid. This is not true when glance calls cinder for attachment in glance cinder configuration. This patch (along with the cinder patch) make the instance_uuid optional and allow glance to do attachments without passing instance_uuid. Change-Id: Ifbaca4aa87d890bc5130069638d42665b914b378
