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.
Fixes: #6430.

For external hypervisors(qemu, cloud-hypervisor, ...), the ns they launch vm in
is different from internal hypervisor(dragonball). And when we doing CreateContainer
hook, we will rely on the netns path. So we add a get_ns_path API.

According to the runtime OCI Spec, there can be some hook
operations in the lifecycle of the container. In these hook
operations, the runtime can execute some commands. There are different
points in time in the container lifecycle and different hook types
can be executed.
In this commit, we are now supporting 4 types of hooks(same in
runtime-go): Prestart hook, CreateRuntime hook, Poststart hook and
Poststop hook.

Replace `cloud_hypervisor_vm_create_cfg()` with a set of `TryFrom` trait
implementations in the new CH specific `convert.rs` to allow the generic
`Hypervisor` configuration to be converted into the CH specific
`VmConfig` type.
Note that device configuration is not currently handled in `convert.rs`
(it's handled in `inner_device.rs`).
This change removes the old hard-coded CH specific configuration.

Send and Sync are automatically derived traits,
if a type is composed entirely of Send or Sync types, then it is Send or Sync.
Almost all primitives are Send and Sync,
so we don't need to implement them manually most of the time.

Add a basic runtime-rs `Hypervisor` trait implementation for Cloud
Hypervisor (CH).
> **Notes:**
>
> - This only supports a default Kata configuration for CH currently.
>
> - Since this feature is still under development, `cargo` features have
> been added to enable the feature optionally. The default is to not enable
> currently since the code is not ready for general use.
>
> To enable the feature for testing and development, enable the
> `cloud-hypervisor` feature in the `virt_container` crate and enable the
> `cloud-hypervisor` feature for its `hypervisor` dependency.

For kata containers, rootfs is used in the read-only way.
EROFS can noticably decrease metadata overhead.
On the basis of supporting the EROFS file system, it supports using the config parameter to switch the file system used by rootfs.

Add cpu resize ability upon upcall communication channel. Runtime could
use ResizeVcpu VmmAction and pass the desired vCPU number to the
Dragonball hypervisor.
Dragonball will trigger the device manager service in guest kernel's

Since the upstream of vmm-sys-utils upgraded to 0.11.0, some crates
automatically upgrade to v0.11.0, and some stay at v0.10.0 ( depending
on how they write version dependency in Cargo toml` which causes the
compile error in runtime-rs.
In order to fix this problem, we need to upgrade all vmm-sys-util
dependencies in runtime-rs to v0.11.0.

The cargo patch in the cargo.toml seems to cause the whole runtime-rs

One of the checks done by cargo-deny is ensuring all crates have a valid
license. As the rust programs import each other, cargo.toml files
without licenses trigger the check. While I could disable this check
this would be bad practice.
This adds an Apache-2.0 license in the Cargo.toml files.
Some of these files already had a header comment saying it is an Apache
license. As the entire project itself is under an Apache-2.0 license, I
assumed all individual components would also be covered under that
license.
