[Libguestfs] [PATCH v2] v2v: -o rhv-upload: Log full imageio response on failure.

[Richard W.M. Jones]

v1 was here:
https://www.redhat.com/archives/libguestfs/2018-June/msg00015.html

v2 fixes all the issues raised in Nir's review.  I tested it against
ovirt-engine-4.2.4.1-1.el7.noarch and it works, although I wasn't
easily able to trigger the error path so that code is not really
tested (except for syntax checking).
