copyBuffer returns and the streams will be closed when error occurs.
If the error contains "blocked by policy" it means the log output is
disabled by policy with "ReadStreamRequest" and "WriteStreamRequest" set
to false. But at this moment, we want the real stream still working (not
be seen) because we might want to enable logging for debugging purpose,
so we repeat copybuffer in this case to avoid streams being closed.

logging/debugging information might probably be disabled in production
due to security consideration, but we'd better provide an approach for
customer to get logging information during runtime, this PR implement
setpolicy function in kata-runtime tools, although it can set whole policy
other than logging.
setpolicy would evokes remote attestation, which means before setting
policy during runtime, user has to reconfigure new policy hash in KBS/AS.

Disable env variable verification to unblock CI, until container
images that don't specify the Env variables will be handled correctly
(see #9239).
Also, mark the image config Env field as optional, thus allowing

The k3s distribution of k8s uses an embedded version of containerd and
configures it to log to a file, not the journal. Hence, although we
collect the journal as a test artifact, we also need to collect the
actual log files for containerd.
Also collect the k3s containerd config files to help with debugging.

The jobs running on garm will collect journal information. The data gathered
is based on the time the tests started running. The $start_time is
exported on run_tests() and used in collect_artifacts(). It happens that
run_tests() and collect_artifacts() are called on different steps of the
workflow and the environment variables aren't preserved between them,
i.e, $start_time exported on the first step is not available on the
subsequents.
To solve that issue, let's save $start_time in the file pointed out by
$GITHUB_ENV that Github actions uses to export variables. In case $GITHUB_ENV is
empty then probably it is running locally outside of Github, so it won't
save the start time value.

Add details to the README for `kata-manager` showing how to list
available hypervisor configs (packaged and local), and switch between
the configurations. Also, update the hypervisors page to show a lot more
detail about the hypervisor configurations, including the "short name"
used by `kata-manager` for switching hypervisor config.
> **Note:**
>
> These changes only apply to the current default golang runtime.

Add new options to allow the configured hypervisor to be changed:
- `-L`: List available _packaged_ hypervisor config short names.
- `-e`: List available _local_ hypervisor config names.
- `-H <hypervisor>`: Install Kata then switch to the specified hypervisor.
- `-S <hypervisor>`: Switch to the specified hypervisor (by config short name [Errors if Kata not installed]).
For example, to install Kata and configure it to use Cloud Hypervisor
with the golang Kata runtime:
```bash
$ kata-manager.sh -H clh
```
To switch back to the default hypervisor:
```bash
$ kata-manager.sh -S default
```
To show details of the available packaged configs:
```bash
$ kata-manager.sh -L
```
To show details of the local configs:
```bash
$ kata-manager.sh -e
```
> **Notes:**
>
> - This change **only** applies to the current default (golang) Kata runtime.
>
> - Although this is mainly for users wishing to switch hypervisor (by
> changing the Kata config file to another of the packaged config files
> provided for specific hypervisors), strictly it allows users to change
> to _any_ config file. For example, if the user has a config file called
> `/etc/kata-containers/configuration-my-custom-config.toml`, they could
> switch to this by running:
>
> ```bash
> $ kata-manager.sh -S my-custom-config

>
> - The "config short names" are the hypervisor specific part of the configuration file name.
> For example, the config short name for file `configuration-qemu.toml` is
> `qemu` and the config short name for `configuration-clh.toml` is `clh`.

The `configure_kata()` function modifies the configuration file to
enable debug. But it was doing this by calling `sed -i` which, by
default, creates a new _file_ from the `configuration.toml` symbolic
link. This defeated the point of the symbolic link which is supposed to
resolve to the local copy of the pristine config file, so we now use
the GNU sed(1) specific `---follow-symlinks` option to retain the
sym-link.

that would break the make test process with SIGSYS after applying
SeccompFilter. In order to fix this, we change the allowlist in this

the mmap region start guest addr hard-code a value and later there
would be check whether the mentioned addr is larger than or equal
to mem_end (default to host_phy_mem >> 1) in order to satisfy the
requirement for DaxMemory. Since github virt machine phy_mem is larger
than previous CI machine we use, the hard-code value could no longer be

PR #8760 tentatively tried to have the shim to run in its own mount
namespace for the sake of improving isolation between the sandbox and
the host. Thus crio storage drivers shouldn't create a PRIVATE
bind mount on their home directory. Otherwise, the container's rootfs
mount wouldn't be propagated to kata runtime's mount namespace, and
kata runtime couldn't access the container's rootfs files.
So, when kata cooperated with crio, crio should set
skip_mount_home=true for its storage overlay.

Until this point the deployed KBS service is only reachable from within
the cluster. This introduces a generic mechanism to apply an Ingress
configuration to expose the service externally.
The first implemened ingress is for AKS. In case the HTTP application
routing isn't enabled in the cluster (this is required for ingress), an
add-on is applied.
It was added the get_cluster_specific_dns_zone() and
enable_cluster_http_application_routing() helper functions
to gha-run-k8s-common.sh.

Kustomize has been used on some of our internal components (e.g.
kata-deploy) to manage k8s deployments. On CI it has been used
the `sed` tool to edit kustomization.yaml files, but `kustomize` is
more suitable for that purpose. So in order to use that tool on CI
scripts in the future, this commit introduces the `install_kustomize()`
function that is going to download and install the binary in
/usr/local/bin in case it's found on $PATH.
