upgrade: adding a docstring for _is_conf_volume_there

The code to detect the configuration image is not trivial so
it's better to describe it.
Since nothing calls prepareImage on the configuration image before
we discover it, the volume shouldn't be available but it is so
it's better to keep track of this behavior.
