We don't have any plans to add it, but if someone's interested we'd
accept patches. It would need to integrate with our virStream APIs
to allow download, in similar way to how virStorageVolDownload() works

What args this function need to receive? VolDownload this args:
virStorageVolDownload(virStorageVolPtr vol,
                      virStreamPtr stream,
                      unsigned long long offset,
                      unsigned long long length,
                      unsigned int flags)

I think that we can use all of this, but instead of vol, what we need to recv?
