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

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.

Kata-monitor detects started and terminated kata pods by monitoring the
vc/sbs fs (this makes sense since we will have to access that path to
access the sockets there to get the metrics from the shim).
While kata-monitor updates its sandbox cache based on the sbs fs events,
it will schedule also a sync with the container manager via the CRI in
order to sync the list of sandboxes there.
The container manager will be the ultimate source of truth, so we will
stick with the response from the container manager, removing the
sandboxes not reported from the container manager.
May happen anyway that when we check the container manager, the new kata
pod is not reported yet, and we will remove it from the kata-monitor pod
cache. If we don't get any new kata pod added or removed, we will not
check with the container manager again, missing reporting metrics about
that kata pod.
Let's stick with the sbs fs as the source of truth: we will update the
cache just following what happens on the sbs fs.
At this point we may have also decided to drop the container manager
connection... better instead to keep it in order to get the kube pod
metadata from it, i.e., the kube UID, Name and Namespace associated with
the sandbox.
Every time we get a new sandbox from the sbs fs we will try to retrieve the
pod metadata associated with it.
Right now we just attach the container manager sandbox id as a label to
the exposed metrics, making hard to link the metrics to the running pod
in the kubernetes cluster.
With kubernetes pod metadata we will be able to add them as labels to map
explicitly the metrics to the kubernetes workloads.

govet checks have been ignored on govmm repo, but those are enabled on
kata-containers one. So, in order to avoid failing our CIs let's just
keep ignoring the checks for the govmm structs and have an issue opened
for fixing it whenever someone has cycles to do it.
The important bit here is, we're not making anything worse that it
already is. :-)

`enable_swap` option was added long time ago to add
`-realtime mlock=off` to the QEMU's command line.
Kata now supports QEMU 6, `-realtime` option has been deprecated and
`mlock=on` is causing unexpected behaviors in kata.
This patch removes support for `enable_swap`, `-realtime` and `mlock=`
since they are causing bugs in kata.
