The add_device() function, from the device manager code, takes a
DeviceConfig as a parameter, instead of a VmAddDevice.
The change was originally done as part of 34412c9b41 and it didn't
break Kata Containers because the VmAddDevice and DeviceConfig structs
share most of their fields, besides the optional for serialization
`pci_segment`, which is not used by the client yet.

Adjust MTU logic such that:
1. Apply an MTU to the TAP interface if the user supplies it
2. Always query the TAP interface for the MTU and expose that.

Add a new "mtu" parameter to the NetConfig structure and therefore to
the --net option. This allows Cloud Hypervisor's users to define the
Maximum Transmission Unit (MTU) they want to use for the network
interface that they create.
In details, there are two main aspects. On the one hand, the TAP
interface is created with the proper MTU if it is provided. And on the
other hand the guest is made aware of the MTU through the VIRTIO
configuration. That means the MTU is properly set on both the TAP on the
host and the network interface in the guest.

Removing the option --tdx to specify that we want to run a TD VM. Rely
on --platform option by adding the "tdx" boolean parameter. This is the
new way for enabling TDX with Cloud Hypervisor.
Along with this change, the way to retrieve the firmware path has been
updated to rely on the recently introduced PayloadConfig structure.

The old API remains usable, and will remain usable for two releases but

The parameter "poll_queue" was useful at the time Cloud Hypervisor was
responsible for spawning vhost-user backends, as it was carrying the
information the vhost-user-block backend should have this option enabled
or not.
It's been quite some time that we walked away from this design, as we
now expect a management layer to be responsible for running vhost-user
backends.
That's the reason why we can remove "poll_queue" from the DiskConfig
structure.

This reverts commit 87eed369cd.
The reason we're reverting this is that OpenAPI Specification[0] doesn't
know how to deal with unsigned types. :-/
Right now the best to do is keep it as it's, as an int64, and try to fix
OpenAPI, or even switch to swagger, as the latter knows how to properly
deal with those. However, switching to swagger is far from being an 1:1
transition and will require time to experiment, thus reverting this for
now seems the best approach.

The Token Bucket fields are, on the Cloud Hypervisor side, u64.
However, we expose those as int64 in the OpenAPI YAML file.
With that in mind, let's adjust the yaml file to expose those as uint64.

Use a single enum member for representing errors from the internal API.
This avoids the ugly duplication of the API call name in the error
message:
e.g.
$ target/debug/ch-remote --api-socket /tmp/api resize --cpus 2
Error running command: Server responded with an error: InternalServerError: VmResize(VmResize(CpuManager(DesiredVCpuCountExceedsMax)))
Becomes:
$ target/debug/ch-remote --api-socket /tmp/api resize --cpus 2
Error running command: Server responded with an error: InternalServerError: ApiError(VmResize(CpuManager(DesiredVCpuCountExceedsMax)))

AMX is an x86 extension adding hardware units for matrix
operations (int and float dot products). The goal of the extension is
to provide performance enhancements for these common operations.
On Linux, AMX requires requesting the permission from the kernel prior
to use. Guests wanting to make use of the feature need to have the
request made prior to starting the vm.
This change then adds the first --cpus features option amx that when
passed will enable AMX usage for guests (needs a 5.17+ kernel) or
exits with failure.
The activation is done in the CpuManager of the VMM thread as it
allows migration and snapshot/restore to work fairly painlessly for
AMX enabled workloads.

As we've added support for cold adding devices to a VM that was created
but not already started, we should propagate the `204` response
generated on those cases to the yaml file, so openapi-generator can

`204` successful results.
