[compute] Add server backup function

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.
