This patch extends virtio-blk emulation to handle zoned device commands

A zone append command is a write operation that specifies the first

Zoned Block Devices (ZBDs) devide the LBA space to block regions called zones
that are larger than the LBA size. It can only allow sequential writes, which
reduces write amplification in SSD, leading to higher throughput and increased
capacity. More details about ZBDs can be found at:
