When creating a container with a raw disk image using virtio-blk,
the guest does not have the upper directory and worker directory present.
Therefore, it is necessary to create these directories before mounting the filesystem with overlay.

We utilize the KataVirtualVolume which storing the dm-verity info
and the path of disk image on the host supplied by snapshotter as an integral part of `CreateContainer`.
Within this process, we copy the verity info and the disk image path to mount slice to create a block device by virtio-blk.
Then storing the `lowerdir` in rootfs.storage which is the mountpoint of the verity path through `CreateContainerRequest`.
To maintain clarity and avoid any need for modification to the `VirtioBlkPciHandler`,we introduce the `DmVerityHandler`.
This dedicated handler is responsible for calling image-rs to create verity device and mount the device to the `lowerdir` within the guest environment.

Kata containers as VM-based containers are allowed to run in the host
netns. That is, the network is able to isolate in the L2. The network
performance will benefit from this architecture, which eliminates as many
hops as possible. We called it a Directly Attachable Network (DAN for
short).
The network devices are placed at the host netns by the CNI plugins. The
configs are saved at {dan_conf}/{sandbox_id}.json in the format of JSON,
including device name, type, and network info. At the very beginning stage,
the DAN only supports host tap devices. More devices, like the DPDK, will
be supported in later versions.
The format of file looks like as below:
```json
{
"netns": "/path/to/netns",
"devices": [{
"name": "eth0",
"guest_mac": "xx:xx:xx:xx:xx",
"device": {
"type": "vhost-user",
"path": "/tmp/test",
"queue_num": 1,

Some vmms, such as dragonball, will actively help us
perform online cpu operations when doing cpu hotplug.
Under the old onlineCpuMem interface, it is difficult
to adapt to this situation.
So we modify the semantics of nb_cpus in onlineCpuMemRequest.
In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
semantics become that the number of online CPUs in the guest
needs to be guaranteed.

- Switch kata-ctl from eprintln!()/println!() to structured logging via
the logging library which uses slog.
- Adds a new create_term_logger() library call which enables printing
log messages to the terminal via a less verbose / more human readable
terminal format with colors.
- Adds --log-level argument to select the minimum log level of printed messages.
- Adds --json-logging argument to switch to logging in JSON format.

sandbox_bind_mounts supports kinds of mount patterns, for example:
(1) "/path/to", default readonly mode.
(2) "/path/to:ro", same as (1).
(3) "/path/to:rw", readwrite mode.
Both support configuration and annotation:
(1)[runtime]
sandbox_bind_mounts=["/path/to", "/path/to:rw", "/mnt/to:ro"]
(2) annotation will alse be supported, restricted as below:
