Image-rs crate image pull/decrypt/decompression/unpack/mount
features are ready now.
With image-rs pull_image API, the downloaded container image layers
will store at IMAGE_RS_WORK_DIR, and generated bundle dir with rootfs
and config.json will be saved under CONTAINER_BASE/cid directory.

The content about systemd in "/proc/self/cgroup" is as:

and in "/prol/self/mountinfo" is as:
30 29 0:26 / /sys/fs/cgroup/systemd rw,nosuid,nodev,noexec,relatime shared:6 - cgroup cgroup rw,xattr,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd
The keys extracted from the two files are the same as "name=systemd". So no need to rename the key to "systemd".

Current hook process is handled by just calling
unwrap() on it, sometime it will cause panic.
By handling all Result type and check the error can
avoid panic.

Pulling image is the most time-consuming step in the container lifecycle. This PR
introduse nydus to kata container, it can lazily pull image when container start. So it
can speed up kata container create and start.

In commit 78dff468bf1 we introduced logic to rewrite PCIDEVICE_ environment
variables for the container so that they contain correct addresses for the
Kata VM rather than for the host. Unfortunately, we never actually invoked
the function to do this.
It turns out we need to do this not only at container creation time, but
also for environment variables supplied to processes exec-ed into the
container after creation (e.g. with crictl exec). Add calls to make both
those updates.

add_devices() generates a mapping of host to guest PCI addresses which is
used to update some environment variables for the workload. Currently it
just does this locally, but it turns out we're going to need the same map
again in order to correct environment variables for processes exec-ed into
the existing container.
Move the map to the sandbox structure so we can keep it around for those
later uses.

This function updates PCIDEVICE_ environment variables (such as those
supplied by the Kubernetes SR-IOV plugin) in the OCI spec to be correct
for the Kata VM, rather than for the host.
We neglected to actually call this function, however, and it turns out that
when we do, we need to do things slightly different. We actually need to
adjust envionment variables both in the OCI spec when creating a container
and also in the variables supplied for exec-ing a new process within an
existing container.
Adjust the function so that it can be used for both these cases.

The tokio's spawn will only create an future async task
instead of a new real thread, thus executing unshare to
create a new namespace in tokio's async task would make
the agent process to join in the new created namespace,
which isn't expected.
Thus, we'd better to to the unshare in a real thread to
prevent moving the agent process into a new namespace.

For calls from shim to agent, the return error will be processed like this:
match self.do_start_container(req).await {
Err(e) => Err(ttrpc_error(ttrpc::Code::INTERNAL, e.to_string())),
Ok(_) => Ok(Empty::new()),
}
The e.to_string() return only a part of the error(for example set by context()),
this may lead lack of information.
The `format!("{:?}", err)` will return more info.
