[Libguestfs] [PATCH 0/5] Fix rhv-upload output

Fix problems in new rhv-upload implementation: - The plugin does not flush to all connections in flush() - The plugin does not close all connections in cleanup() - Idle connections are closed in imageio server, and we don't have a safe way to recover. - virt-v2v try to get disk allocation using imageio output, but imageio output does not support extents. Even if imageio output will support extents, the call is done after the transfer was finalized so it does not have access to storage. Problems not fixed yet: - Image transfer is finalized *before* closing the connection to imageio - this will always time out with RHV < 4.4.9, and succeeds by mistake with RHV 4.4.9 due to a regression that will be fixed in 4.4.10. This will be a non-issue in next RHV version[1]. To support older RHV versions, virt-v2v must finalize the image transfer *after* closing the output. Tested on RHEL 8.6 with upstream nbdkit and libnbd.
