We need to do proper sandbox sizing when we're doing cold-plug introduce CDI,
the de-facto standard for enabling devices in containers. containerd
will pass-through annotations for accumulated CPU,Memory and now CDI
devices. With that information sandbox sizing can be derived correctly.

Currently, even when using devmapper, if the VMM supports virtio-fs /
virtio-9p, that's used to share a few files between the host and the
guest.
This *needed*, as we need to share with the guest contents like secrets,
certificates, and configurations, via Kubernetes objects like configMaps
or secrets, and those are rotated and must be updated into the guest
whenever the rotation happens.
However, there are still use-cases users can live with just copying
those files into the guest at the pod creation time, and for those
there's absolutely no need to have a shared filesystem process running
with no extra obvious benefit, consuming memory and even increasing the
attack surface used by Kata Containers.
For the case mentioned above, we should allow users, making it very
clear which limitations it'll bring, to run Kata Containers with
devmapper without actually having to use a shared file system, which is
already the approach taken when using Firecracker as the VMM.

In order to support different pod VM instance type via
remote hypervisor implementation (cloud-api-adaptor),
we need to pass machine_type, default_vcpus
and default_memory annotations to cloud-api-adaptor.
The cloud-api-adaptor then uses these annotations to spin
up the appropriate cloud instance.

The `-o` option is the legacy way to configure virtiofsd, inherited
from the C implementation. The rust implementation honours it for
compatibility but it logs deprecation warnings.
Let's use the replacement options in the go shim code. Also drop
references to `-o` from the configuration TOML file.

The C implementation of virtiofsd had some kind of limited support
for remote POSIX locks that was causing some workflows to fail with
kata. Commit 432f9bea6e hard coded `-o no_posix_lock` in order
to enforce guest local POSIX locks and avoid the issues.
We've switched to the rust implementation of virtiofsd since then,
but it emits a warning about `-o` being deprecated.
According to https://gitlab.com/virtio-fs/virtiofsd/-/issues/53 :
The C implementation of the daemon has limited support for
remote POSIX locks, restricted exclusively to non-blocking
operations. We tried to implement the same level of
functionality in #2, but we finally decided against it because,
in practice most applications will fail if non-blocking
operations aren't supported.
Implementing support for non-blocking isn't trivial and will
probably require extending the kernel interface before we can
even start working on the daemon side.
There is thus no justification to pass `-o no_posix_lock` anymore.

Some vmms, such as dragonball, will actively help us
perform online cpu operations when doing cpu hotplug.
Under the old onlineCpuMem interface, it is difficult
to adapt to this situation.
So we modify the semantics of nb_cpus in onlineCpuMemRequest.
In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
semantics become that the number of online CPUs in the guest
needs to be guaranteed.

Instead of setting:
```
firmware = "/path/to/OVMF.fd"
firmware_volume = "/path/to/OVMF_VARS.fd"
```
We should either be setting:
```
firmware = "/path/to/OVMF.fd"
```
Or:
```
firmware = "/path/to/OVMF_CODE.fd"
firmware_volume = "/path/to/OVMF_VARS.fd"
```
I'm taking the approach to setting up the latter, as that's what's been
tested as part of our TDX CI.

There is a race condition when virtiofsd is killed without finishing all
the clients. Because of that, when a pod is stopped, QEMU detects
virtiofsd is gone, which is legitimate.
Sending a SIGTERM first before killing could introduce some latency
during the shutdown.

If a hypervisor debug console is enabled and sandbox_cgroup_only is set,
the hypervisor can fail to open /dev/ptmx, which prevents the sandbox
from launching.
This is caused by the absence of a device cgroup entry to allow access
to /dev/ptmx. When sandbox_cgroup_only is not set, the hypervisor
inherits the default unrestrcited device cgroup, but with it enabled it
runs into allow / deny list restrictions.
Fix by adding an allowlist entry for /dev/ptmx when debug is enabled,
sandbox_cgroup_only is true, and no /dev/ptmx is already in the list of
devices.
