Here we use vfu-tgt library and emulate a virtio-blk device
as the first use case of vfu-tgt library.
Usage example with QEMU:
1. build/bin/spdk_tgt
2. scripts/rpc.py bdev_malloc_create -b malloc0 $((512)) 512
3. scripts/rpc.py vfu_virtio_create_blk_endpoint vfu.0 --bdev-name malloc0 \
--cpumask=0x1 --num-queues=2 \
--qsize=256 --packed-ring
4. Start QEMU with '-device vfio-user-pci,socket=/spdk/vfu.0'
