1. when we use nerdctl to setup network for kata, no netns is created by
nerdctl, kata need to create netns by its own
2. after start VM, nerdctl will call cni plugin via oci hook, we need to
rescan the netns after the interfaces have been created, and hotplug
the network device into the VM

As the QEMU configuration for TDX differs quite a lot from the normal
QEMU configuration, let's add a new configuration file for the QEMU TDX.

Since TDX doesn't support readonly memslot, TDVF cannot be mapped as
pflash device and it actually works as RAM. "-bios" option is chosen to
load TDVF.
OVMF is the opensource firmware that implements the TDVF support. Thus
the command line to specify and load TDVF is ``-bios OVMF.fd``

This change provides a preliminary implementation for the Cloud Hypervisor (CH) feature ([currently
disabled](https://github.com/kata-containers/kata-containers/pull/6201))
to allow it to generate the CH configuration for handling confidential guests.
This change also introduces concrete errors using the `thiserror` crate
(see `src/runtime-rs/crates/hypervisor/ch-config/src/errors.rs`) and a
lot of unit tests for the conversion code that generates the CH
configuration from the generic Hypervisor configuration.

This PR is a continuing work for (kata-containers#3679).
This generalizes the previous VFIO device handling which only
focuses on PCI to include AP (IBM Z specific).
Fixes: kata-containers#3678
Signed-off-by: Hyounggyu Choi <Hyounggyu.Choi@ibm.com>
Initial VFIO-AP support (#578) was simple, but somewhat hacky; a
different code path would be chosen for performing the hotplug, and
agent-side device handling was bound to knowing the assigned queue
numbers (APQNs) through some other means; plus the code for awaiting
them was written for the Go agent and never released. This code also
artificially increased the hotplug timeout to wait for the (relatively
expensive, thus limited to 5 seconds at the quickest) AP rescan, which
is impractical for e.g. common k8s timeouts.
Since then, the general handling logic was improved (#1190), but it
assumed PCI in several places.
In the runtime, introduce and parse AP devices. Annotate them as such
when passing to the agent, and include information about the associated
APQNs.
The agent awaits the passed APQNs through uevents and triggers a
rescan directly.

Generalize VFIO devices to allow for adding AP in the next patch.
The logic for VFIOPciDeviceMediatedType() has been changed and IsAPVFIOMediatedDevice() has been removed.
The rationale for the revomal is:
- VFIODeviceMediatedType is divided into 2 subtypes for AP and PCI
- Logic of checking a subtype of mediated device is included in GetVFIODeviceType()
- VFIOPciDeviceMediatedType() can simply fulfill the device addition based
on a type categorized by GetVFIODeviceType()

e.g., split_vfio_option is PCI-specific and should instead be named
split_vfio_pci_option. This mutually affects the runtime, most notably
how the labels are named for the agent.

When calling `MAKE_KERNEL_NAME` we're considering the default kernel
name will be `vmlinux.container` or `vmlinuz.container`, which is not
the case as the runtime-rs, when used with dragonball, relies on the
`vmlinu[zx]-dragonball-experimental.container` kernel.
Other hypervisors will have to introduce a similar
`MAKE_KERNEL_NAME_${HYPERVISOR}` to adapt this to the kernel they want
to use, similarly to what's already done for the go runtime.
By doing this we also ensure that no changes in the configuration file
will be required to run runtime-rs, with dragonball, as part of our CI
or as part of kata-deploy.
