In the current doc, the command examples are like "os server create" but the acutal command should be started with "openstack" instead of "os", it is misleading to first time users. Change-Id: Ie67c0152d8ff8b7c456f91dc8b9a9164437ee9d1
Add server backup function There is no return value for this command per following doc http://developer.openstack.org/api-ref-compute-v2.1.html#createBackup, also novaclient can't be updated now due to backward compatible issue http://lists.openstack.org/pipermail/openstack-dev/2016-March/089376.html, so we have to get the information ourselves. The Image tests were not using warlock images, so that needed to be fixed before we could completely test things like --wait. Change-Id: I30159518c4d3fdec89f15963bda641a0b03962d1
