Use create_image_from_server to create image for server

This is to use create_image_from_server to create a server image
with multibyte character image name, for the following reasons:
1. deleting image without waiting for it to be active has the potential
   risk of encounting Conflict exception, like
       {u\'message\': u"Cannot 'delete' instance 16d8c500-cd69-4246-964a-39173d451991
                       while it is in task_state image_snapshot",
        u\'code\': 409}
2. using create_image_from_server will make code look cleaner.
