It is important that we continue to support VirtIO-SCSI. While
VirtIO-BLK is a common choice, virtio-scsi offers significant
performance advantages in specific scenarios, particularly when
utilizing iothreads and with NVMe Fabrics.
Maintaining Flexibility and Choice by supporting both virtio-blk and
virtio-scsi, we provide greater flexibility for users to choose the
optimal storage（virtio-blk, virtio-scsi) interface based on their
specific workload requirements and hardware configurations.
As virtio-scsi controller has been created when qemu vm starts with
block device driver is set to `virtio-scsi`. This commit is for blockdev_add
the backend block device and device_add frondend virtio-scsi device via qmp.

As block device index is an very important unique id of a block device
and can indicate a block device which is equivalent to device_id.
In case of index is required in calculating scsi LUN and reduce
useless arguments within reusing `hotplug_block_device`, we'd better
change the device_id with block device index.

It supports handling scsi device when block device driver is `scsi`.
And it will ensure a correct storage source with LUN.

AIO is the I/O mechanism used by qemu with options:
- threads
Pthread based disk I/O.
- native

- io_uring (default mode)

Although Previous implementation of hotplugging block device via QMP
can successfully hot-plug the regular file based block device, but it
fails when the backend is /dev/xxx(e.g. /dev/loop0). With analysis about
it, we can know that it lacks the ablility to hotplug host block devices.
This commit will fill the gap, and make it work well for host block
devices.

For the release itself, let's simply copy the VERSION file to the
tarball.
To do so, we had to change the logic that merges the build, as at that
point the tag is not yet pushed to the repo.

On commit 90bc749a19, we've changed the

the non-GPU TDX use-case, which depends on the distro binary.

According to the issue [1], Tokio will panic when we are giving a blocking
socket to Tokio's `from_std()` method, the information is as follows:
```
A panic occurred at crates/agent/src/sock/vsock.rs:59: Registering a
blocking socket with the tokio runtime is unsupported. If you wish to do
anyways, please add `--cfg tokio_allow_from_blocking_fd` to your RUSTFLAGS.
```
A workaround is to set the socket to non-blocking.
