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.

StartContainer will be execute in guest container namespace in Kata.
The Hook Path of this kind of hook is also in guest container namespace.
StartContainer is executed after start operation is called, and it
should be executed before user-specific command is executed.

CreateContainer hook is one kind of OCI hook. In kata, it will be
executed after VM is started, before container is created, and after
CreateRuntime is executed.
The hook path of CreateContainer hook is in host runtime namespace, but
it will be executed in host vmm namespace.

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.

Allow an initrd/initramfs image to be used with Cloud Hypervisor, which
is handled differently to the default rootfs image type.

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.

This reverts commit 9d78bf9086.
Golang binaries are built statically by default, unless linking against
CGO, which we do. In this case we dynamically link against glibc,
causing us troubles when running a binary built with Ubuntu 22.04 on
Ubuntu 20.04 (which will still be supported for the next few years ...)

When starting an initrd the kernel expects to find /dev/console in the initrd,
so that it can connect it as stdin/stdout/stderr to the /init process. If the
device node is missing the kernel will complain that it was unable to open an
initial console. If kata-agent is the initrd init process, it will also result
in log messages not being logged to console and thus not forwarded to host
syslog.
Add a set of standard device nodes for completeness, so that console logging
works. To do that we install the makedev packge which provides a MAKEDEV helper
that knows the major/minor numbers. Unfortunately the debian package tries to
create devnodes from postinst, which can be suppressed if systemd-detect-virt
is present. That's why we create a small dummy script that matches what
systemd-detect-virt would output (anything is enough to suppress mknod).

Let's push the builder images to a registry, so we can take advantage of
those on each step of our building process.
Signed-off-by: Fabiano Fidêncio <fabiano.fidencio@intel.com>
This, combined with the effort of caching builder images *and* only
performing the build itself inside the builder images, is the very first
step for reproducible builds for the project.
Reproducible builds are quite important when we talk about Confidential
Containers, as users may want to verify the content used / provided by
the CSPs, and this is the first step towards that direction.
