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.

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.
