There are many errors in the patchs which passed our XenServer CI,
it is because when run tempest, test case will ask nova sevice to
do snapshotting, then delete image before snapshotting done. Then
nova compute service couldn't find the image when do image upload
and raise an exception.
Normally the exception can be consumed by nova service. But the
exception generated by os-xenapi can't be recognized by nova, so
the error logs come out.
Add a exception in os_xenapi/client to mark image not found
exception and convert it to another exception which computer
service can process in nova/virt/xenapi.
