German Maglione, one of the current virtio-fs developers, has brought to
our attention that using "announce-submounts" could help us to prevent
inode number collisions.
This feature was introduced a year ago or so by Hanna Reitz as part of
the 08dce386e77eb9ab044cb118e5391dc9ae11c5a8, and as we already mandate
QEMU >= 6.1.0, let's take advantage of that.

Change the variables `mountTypeFieldIdx := 8`, `mntDestIdx := 4` and `netNsMountType := "nsfs"` to const.
And unify the variable naming style, modify `mntDestIdx` to `mountDestIdx`.

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.

We are converting the Network structure into an interface, so that
different host OSes can have different networking implementations for
Kata.
One step into that direction is to rename all the Network structure
fields and methods to something that is less Linux networking namespace
specific. This will make the Network interface naming consistent.

We are replacing the NetworkingNamespace structure with the Network

Remove unused parameters.
Reduce the number of parameters by deriving some of them (e.g. a

Endpoints creations, attachement and hotplug are bound to the networking
namespace described through the Network structure.
Making them Network methods is natural and simplifies the code.

For simplicity sake, there should only be one networking structure per
sandbox, as opposed to two (Network and NetworkingNamespace) currently.
This commit start expanding the Network structure in order to eventually
make it the single representation of a virtcontainers sandbox

There are software and hardware architectures which do not support
dynamically adjusting the CPU and memory resources associated with a
sandbox. For these, today, they rely on "default CPU" and "default
memory" configuration options for the runtime, either set by annotation
or by the configuration toml on disk.
In the case of a single container (launched by ctr, or something like
"docker run"), we could allow for sizing the VM correctly, since all of
the information is already available to us at creation time.
In the sandbox / pod container case, it is possible for the upper layer
container runtime (ie, containerd or crio) could send a specific
annotation indicating the total workload resource requirements
associated with the sandbox creation request.
In the case of sizing information not being provided, we will follow
same behavior as today: start the VM with (just) the default CPU/memory.
If this information is provided, we'll track this as Workload specific
resources, and track default sizing information as Base resources. We
will update the hypervisor configuration to utilize Base+Workload
resources, thus starting the VM with the appropriate amount of CPU and
memory.
In this scenario (we start the VM with the "right" amount of
CPU/Memory), we do not want to update the VM resources when containers
are added, or adjusted in size.
This functionality is introduced behind a configuration flag,
`static_sandbox_resource_mgmt`. This is defaulted to false for all
configurations except Firecracker, which is set to true.
This'll greatly improve UX for folks who are utilizing
Kata with a VMM or hardware architecture that doesn't support hotplug.
Note, users will still be unable to do in place vertical pod autoscaling
or other dynamic container/pod sizing with this enabled.
