d2f17ee55a packaging: Use the $BUILD_SUFFIX when renaming the qemu binary
Instead of always naming the binary as "-experimental", let's take
advantage of the $BUILD_SUFFIX that's already passed and correctly name
the binary according to it.

516ed240f4 packaging: Allow building a TDX capable kernel
We're adding a new target for building a TDX capable kernel for CC.
This commit, differently than c4cc16efcd,
introduces support for building the artefacts that are TEE specific.

423162d2aa kernel: Allow passing the URL to download the tarball
Passing the URL to be used to download the kernel tarball is useful in
various scenarios, mainly when doing a downstream build, thus let's add
this new option.

This new option also works around a known issue of the Dockerfile used
to build the kernel not having `yq` installed.

965c0b1ad2 kernel: Deduplicate code used for building TEE kernels
There's no need to have the entire function for building SEV / TDX
duplicated.

Let's remove those functions and create a `get_tee_kernel()` which takes
the TEE as the argument.

df0cc78e57 kata-deploy-cc: Introduce the new kata-deploy for CC
Although I don't like the duplication introduced here, it's (at least
for now) way cleaner to have a specific daemonset for the Confidential
Containers effort.

As soon as we have all the bits and pieces upstreamed (kernel, QEMU, and
specific dependencies for each one of the TEEs), we'll be easily able to
get rid of this one.  However, for now, focusing on this different set
of files will make our lives easier.

This new daemonset includes the configurations needed for containerd in
order to use the `cc` specific `cri_handler`, which is not and will not
be upstream on the containerd side.

Note, CRI-O is **not** supported for now.

f4eea832a1 release: Adapt kata-deploy for 2.5.0-rc0
kata-deploy files must be adapted to a new release.  The cases where it
happens are when the release goes from -> to:
* main -> stable:
  * kata-deploy-stable / kata-cleanup-stable: are removed

* stable -> stable:
  * kata-deploy / kata-cleanup: bump the release to the new one.

There are no changes when doing an alpha release, as the files on the
"main" branch always point to the "latest" and "stable" tags.

4e48509ed9 build: Set safe.directory for runtime repo
While doing a docker build for shim-v2, we see this:

```
fatal: unsafe repository
('/home/${user}/go/src/github.com/kata-containers/kata-containers' is
owned by someone else)
To add an exception for this directory, call:

        git config --global --add safe.directory
/home/${user}/go/src/github.com/kata-containers/kata-containers
```

This is because the docker container build is run as root while the
runtime repo is checked out as normal user.

Unlike this error causing the rootfs build to error out, the error here
does not really cause `make shim-v2-tarball` to fail.

However its good to get rid of this error message showing during the
make process.

2a4fbd6d8c agent: enhance get handled signal
For runC, send the signal to the init process directly.
For kata, we try to send `SIGKILL` instead of `SIGTERM` when the process
has not installed the handler for `SIGTERM`.
The `is_signal_handled` function determine which signal the container
process has been handled. But currently `is_signal_handled` is only
catching (SigCgt). While the container process is ignoring (SigIgn) or
blocking (SigBlk) also should not be converted from the `SIGTERM` to
`SIGKILL`. For example, when using terminationGracePeriodSeconds the k8s
will send SIGTERM first and then send `SIGKILL`, in this case, the
container ignores the `SIGTERM`, so we should send the `SIGTERM` not the
`SIGKILL` to the container.
