Let's add a `default_maxmemory` configuration, which allows the admins
to set the maximum amount of memory to be used by a VM, considering the
initial amount + whatever ends up being hotplugged via the pod limits.
By default this value is 0 (zero), and it means that the whole physical
RAM is the limit.

Policy for whats valid/invalid within the config varies by VMM, host,
and by silicon architecture. Let's keep katautils simple for just
translating a toml to the hypervisor config structure, and leave
validation to virtcontainers.
Without this change, we're doing duplicate validation.

Enable "-sandbox on" in qemu can introduce another protect layer
on the host, to make the secure container more secure.
The default option is disable because this feature may introduce some
performance cost, even though user can enable
/proc/sys/net/core/bpf_jit_enable to reduce the impact.

This is the disk counterpart of the what was introduced for the network
as part of the previous commits in this series.
The newly added fields are:
* DiskRateLimiterBwMaxRate, defined in bits per second, which is used to
control the network I/O bandwidth at the VM level.
* DiskRateLimiterBwOneTimeBurst, also defined in bits per second, which
is used to define an *initial* max rate, which doesn't replenish.
* DiskRateLimiterOpsMaxRate, the operations per second equivalent of the
DiskRateLimiterBwMaxRate.
* DiskRateLimiterOpsOneTimeBurst, the operations per second equivalent of
the DiskRateLimiterBwOneTimeBurst.
For now those extra fields have only been added to the hypervisor's
configuration and they'll be used in the coming patches of this very

In a similar way to what's already exposed as RxRateLimiterMaxRate and
TxRateLimiterMaxRate, let's add four new fields to the Hypervisor's
configuration.
The values added are related to bandwidth and operations rate limiters,
which have to be added so we can expose I/O throttling configurations to
users using Cloud Hypervisor as their preferred VMM.
The reason we cannot simply re-use {Rx,Tx}RateLimiterMaxRate is because
Cloud Hypervisor exposes a single MaxRate to be used for both inbound
and outbound queues.
The newly added fields are:
* NetRateLimiterBwMaxRate, defined in bits per second, which is used to
control the network I/O bandwidth at the VM level.
* NetRateLimiterBwOneTimeBurst, also defined in bits per second, which

SetupOCIConfigFile creates a temporary directory with os.MkDirTemp(). This
means the callers need to register a deferred function to remove it again.
At least one of them was commented out meaning that a /temp/katatest-

Previously, it was not permitted to have neither an initrd nor an image.
However, this is the exact config to use for Secure Execution, where the

Also
- remove redundant code for image/initrd checking -- no need to check in

`getInitrdAndImage` (called)
- use `QemuCCWVirtio` constant when possible

src/runtime/virtcontainers/hook/mock contains a simple example hook in Go.
The only thing this is used for is for some tests in

Running unit tests should generally have minimal dependencies on
things outside the build tree. It *definitely* shouldn't modify
system wide things outside the build tree. Currently the runtime
"make test" target does so, though.
Several of the tests in src/runtime/pkg/katautils/hook_test.go require a
sample hook binary. They expect this hook in
/usr/bin/virtcontainers/bin/test/hook, so the makefile, as root, installs
the test binary to that location.
Go tests automatically run within the package's directory though, so
there's no need to use a system wide path. We can use a relative path to
the binary build within the tree just as easily.

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.
