v2v: Add -o rhv-upload output mode (RHBZ#1557273).
PROBLEMS: - -of qcow2 does not work, with multiple problems * needs to set NBD size to something larger than virtual size - Not tested against imageio which supports zero/trim/flush. This adds a new output mode to virt-v2v. virt-v2v -o rhv-upload streams images directly to an oVirt or RHV >= 4 Data Domain using the oVirt SDK v4. It is more efficient than -o rhv because it does not need to go via the Export Storage Domain, and is possible for humans to use unlike -o vdsm. The implementation uses the Python SDK (‘ovirtsdk4’ module). An nbdkit Python 3 plugin translates NBD calls from qemu into HTTPS requests to oVirt via the SDK. (cherry picked from commit 719a2725714cb3d0ae06cb6aa01e2849ec167bec)
