So when we create container with the glance api, we can specify the container's format
and the image format is not important because the OVF packaging has included the all detail
description about the image. In the first demo,we just do as few as possible to change
the glance's constructure.But a obvious problem, the code is not elegant and need to refactor.
This is part goal of next stage.
