This patch adds keep_abnormal in runtime config. If keep_abnormal =
true, it means that 1) if the runtime exits abnormally, the cleanup
process will be skipped, and 2) the runtime will not exit even if the
health check fails.
This option is typically used to retain abnormal information for
debugging and should NOT be enabled by default.

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

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.

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.

Currently, we only create the new exec process in runtime, this will cause error
when the following requests needing to be handled:
- Task: exec process
- Task: resize process pty
- ...
The agent do not do_exec_process when we handle ExecProcess, thus we can not find
any process information in the guest when we handle ResizeProcessPty. This will
report an error.
In this commit, the handling process is modified to the:
* Modify process tty_win information in runtime
* If the exec process is not running, we just return. And the truly pty_resize will
happen when start_process

In some cases, network endpoints will be configured through Prestart
Hook. So network endpoints may need to be added(hotpluged) after vm
is started and also Prestart Hook is executed.
We move pre-start hook functions' execution to sandbox_start to allow
hooks running between vm_start and netns_scan easily, so that the
lifecycle API can be cleaner.

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.

runtime-go): Prestart hook, CreateRuntime hook, Poststart hook and
Poststop hook.
