Description of problem:

http://libguestfs.org/virt-v2v.1.html#output-to-rhv

Currently -o rhv uses the oVirt/RHV Export Storage Domain (ESD).
This concept has been deprecated and is going to be removed.

There are APIs for creating guests and uploading disks and
we should use those instead:

http://ovirt.github.io/ovirt-engine-api-model/
http://ovirt.github.io/ovirt-engine-api-model/master/#services/vms

Version-Release number of selected component (if applicable):

libguestfs <= 1.38 uses the ESD.

Additional info:

Should we "save" the ESD method, eg. renaming it to -o rhvesd, or
should we just remove it?
