kata-shim was not reporting `inactive_file` in memory stat.
This memory is deducted by containerd when calculating the size of container working set, as it can be paged out by the operating
system under memory pressure. Without reporting `inactive_file`, containerd will over report container memory usage.
[Here](https://github.com/containerd/containerd/blob/v1.7.22/pkg/cri/server/container_stats_list_linux.go#L117) is where containerd
deducts `inactive_file` from memory usage.
Note that kata-shim correctly reports `total_inactive_file` for cgroup v1, but this was not implemented for cgroup v2.
This commit:
- Adds code in kata-shim to report "inactive_file" memory for cgroup v2
- Implements reporting of all available cgroup v2 memory stats to containerd
- Uses defensive coding to avoid assuming existence of any memory.stat fields
The list of available cgroup v2 memory stats defined by containerd can be found
[here](https://pkg.go.dev/github.com/containerd/cgroups/v2/stats#MemoryStat).

This is a quick and simple pre-req for supporting initData, which will

While already adding mrconfigid, which is hardcoded empty right now,
let's do the same for mrowner and mrownerconfig, and leave it prepared
for future expansions.

The current implementation for device binding using driver bind/unbind
and new_id fails in the scenario when the physical device is not bound
to a driver before assigning it to vfio.
There exists and updated mechanism to accomplish the same that does not
have the same issue as above.
The driver_override field for a device allows us to specify the driver for a device
rather than relying on the bound driver to provide a positive match of the
device. It also has other advantages referenced here:
https://patchwork.kernel.org/project/linux-pci/patch/1396372540.476.160.camel@ul30vt.home/
So use the updated driver_override mechanism for binding/unbinding a
physical device/virtual function to vfio-pci.

In Kubernetes we still do not have proper VM sizing
at sandbox creation level. This KEP tries to mitigates
that: kubernetes/enhancements#4113 but this can take
some time until Kube and containerd or other runtimes
have those changes rolled out.
Before we used a static config of VFIO ports, and we
introduced CDI support which needs a patched contianerd.
We want to eliminate the patched continerd in the GPU case
as well.

By default QGS runs on vsock port 4050, but can be modified by the host owner.
Format of the qemu object follows the SocketAddress structure, so it needs to be provided in the JSON format, as in the example below:

The go rand.Seed docs: https://pkg.go.dev/math/rand@go1.20#Seed

> If Seed is not called, the generator is seeded randomly at program startup.
