Under normal circumstances, the virtual machine only requests memory
from the host and does not actively release it back to host when it is
no longer needed, leading to a waste of memory resources.
Free page reporting is a sub-feature of virtio-balloon. When this
feature is enabled, the Linux guest kernel will send information about
released pages to dragonball via virtio-balloon, and dragonball will
then release these pages.
This commit adds an option enable_balloon_f_reporting to runtime-rs.
When this option is enabled, runtime-rs will insert a virtio-balloon
device with the f_reporting option enabled during the Dragonball virtual
machine startup.

This reverts commit 41b7577f08.
We were seeing a lot of issues in the TDX CI of the nature:
"Error: failed to create containerd container: create instance
470: object with key "470" already exists: unknown"
With the TDX CI, we moved to having the nydus snapsotter pre-installed.
Essentially the `deploy-snapshotter` step was performed once before any
actual CI runs.
We were seeing failures related to the error message above.
On reverting this change, we are no longer seeing errors related to
"key exists" with the TDX CI passing now.
The change reverted here is related to downloading incomplete images, but this
seems to be messing up TDX CI.
It is possible to pass --snapshotter to `ctr image check` but that does
not seem to have any effect on the data set returned.

In certain environments (e.g., those with lower performance), `k8s_create_pod()`
may require additional wait time, especially when dealing with large images.
Since `k8s_wait_pod_be_ready()` — which is called by `k8s_create_pod()` — already
accepts `wait_time` as a second argument, it makes sense to introduce `wait_time`
to `k8s_create_pod()` and propagate it to the callee.
This commit adds `wait_time` to `k8s_create_pod()` as the 2nd (optional) argument.

Some of the tests call set_metadata_annotation() for updating the kernel
parameters. For `kata-qemu-se`, repack_secure_image() is called which is
defined in `lib_se.sh` and sourced by `confidential_kbs.sh`.
This commit ensures that the function call chain for the relevant
`KATA_HYPERVISOR` is properly handled.

The configuration is commented out with specifying a default value (50s) because

To make the `cdh_api_timeout` variable configurable, it has been added to
the `AgentConfig` structure.
This change includes storing the variable as a `time::Duration` type and
generalizing the existing `hotplug_timeout` code to handle both timeouts.

The deploy-kbs.sh script generates the kbs.key that's used to install
KBS. This same file is used lately by kbs-client to authenticate. This ensures
that the file was created, otherwise fail.
Another problem solved here is that on bare-metal machines the key doesn't survive
a reboot as it is created in a temporary directory (/tmp/trustee). So let's save
the file to a non-temporary location.
