Some cni plugins will set the MTU of some routes, such as cilium will
modify the MTU of the default route. If the mtu of the route is not set
correctly, it may cause excessive fragmentation or even packet loss of
network packets. Therefore, this PR adds the setting of the MTU of the
route. First, when obtaining the route, if the MTU is set, the MTU will
also be obtained and set to the route in the guest.

Kata-agent now will check if a device /dev/vd* with 'initdata' magic
number exists. If it exists, kata-agent will try to read it. Bytes 9~16
are the length of the compressed initdata toml in little endine.
Bytes starting from 17 is the compressed initdata.
The initdata image device layout looks like
0 8 16 16+length ... EOF
'initdata' length gzip(initdata toml) paddings
The initdata will be parsed and put as aa.toml, cdh.toml and
policy.rego to /run/confidential-containers/initdata.
When AgentPolicy is initialized, the default policy will be overwritten
by that.
When AA is to be launched, if initdata is once processed, the launch arg
will include --initdata parameter.
Also, if
/run/confidential-containers/initdata/aa.toml exists, the launch args
will include -c /run/confidential-containers/initdata/aa.toml.
When CDH is to be launched, if initdata is once processed, the launch
args will include -c /run/confidential-containers/initdata/cdh.toml

As reported in #11011, mounted secrets are available after
a container image is pulled by add_storage() for IBM SE.
But secure mount should be handled before the `add_storage()`.
Therefore, this commit divides cdh_handler() into:
- cdh_handler_trusted_storage()
- cdh_handler_sealed_secrets()
and calls cdh_handler_sealed_secrets() after add_storage()
while keeping cdh_handler_trusted_storage() unchanged.

Kata Containers has support for both the IBM Secure Execution trusted
execution environment and the IBM Crypto Express hardware security
module (used via the Adjunct Processor bus), but using them together
requires specific steps.
In Secure Execution, the Acceleration and Enterprise PKCS11 modes of
Crypto Express are supported. Both modes require the domain to be
_bound_ in the guest, and the latter also requires the domain to be
_associated_ with a _guest secret_. Guest secrets must be submitted to
the ultravisor from within the guest.
Each EP11 domain has a master key verification pattern (MKVP) that can
be established at HSM setup time. The guest secret and its ID are to
be provided at `/vfio_ap/{mkvp}/secret` and
`/vfio_ap/{mkvp}/secret_id` via a key broker service respectively.
Bind each domain, and for each EP11 domain,
- get the secret and secret ID from the addresses above,
- submit the secret to the ultravisor,
- find the index of the secret corresponding to the ID, and
- associate the domain to the index of this secret.
To bind, add the secret, parse the info about the domain, and
associate, the s390_pv_core crate is used. The code from this crate
also does the AP online check, which can be removed from here.

Since some files generated by protobuf were share between
runtime-rs and kata agent, and the kata agent's dependency
image-rs dependened protobuf@3.7.1, thus we'd better to keep
the protobuf version aligned between runtime-rs and agent,
otherwise, we couldn't compile the runtime-rs and agent
at the same time.

The previous PR mistakenly set all perms to 0o666 we should follow
what runc does and fetch the permission from the guest aka host
if the file_mode == 0. If we do not find the device on the guest aka
host fallback to 0.

We had the default permissions set to 0o000 if the file_mode was not
present, for most container devices this is the wrong default. Since
those devices are meant also to be accessed by users and others add a
sane default of 0o666 to devices that do not have any permissions set.
Otherwise only root can acess those and we cannot run containers as a
user.

In the CI, test containers intermittently fail to start after creation,
with an error like below (see #10872 for more details):
# State: Terminated
# Reason: StartError
# Message: failed to start containerd task "afd43e77fae0815afbc7205eac78f94859e247968a6a4e8bcbb987690fcf10a6": No such file or directory (os error 2)
I've observed this error to repro with the following containers, which
have in common that they're all *very short-lived* by design (more tests
might be affected):
* k8s-job.bats
* k8s-seccomp.bats
* k8s-hostname.bats
* k8s-policy-job.bats
* k8s-policy-logs.bats
Furthermore, appending a `; sleep 1` to the command line for those
containers seemed to consistently get rid of the error.
Investigating further, I've uncovered a race between the end of the container
process and the setting up of the cgroup watchers (to report OOMs).
If the process terminates first, the agent will try to watch cgroup
paths that don't exist anymore, and it will fail to start the container.
The added error context in notifier.rs confirms that the error comes
from the missing cgroup:
https://github.com/kata-containers/kata-containers/actions/runs/13450787436/job/37585901466#step:17:6536
The fix simply consists in creating the watchers *before* we start the
container but still *after* we create it -- this is non-blocking, and IIUC the
cgroup is guaranteed to already be present then.
