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.

Device paths may be empty. PciPath resolves this by being a list that

This patch adds the support of the remote hypervisor type for runtime-rs.
The cloud-api-adaptor needs the annotations and network namespace path
to create the VMs.
The remote hypervisor opens a UNIX domain socket specified in the config
file, and sends ttrpc requests to a external process to control sandbox
VMs.

This commit transitions the data implementation for OCI Spec
from kata-oci-spec to oci-spec-rs. While both libraries adhere
to the OCI Spec standard, significant implementation details
differ. To ensure data exchange through TTRPC services, this
commit reimplements necessary data conversion logic.
This conversion bridges the gap between oci-spec-rs data and
TTRPC data formats, guaranteeing consistent and reliable data
transfer across the system.

- The response message returned by the ttRPC `GetGuestDetails()` API.

Currently in the kata container, every io read/write operation requires
an RPC request from the runtime to the agent. This process involves
data copying into/from an RPC request/response, which are high overhead.
To solve this issue, this commit utilize the vsock fd passthrough, a
newly introduced feature in the Dragonball hypervisor. This feature
allows other host programs to pass a file descriptor to the Dragonball
process, directly as the backend of an ordinary hybrid vsock connection.
The runtime-rs now utilizes this feature for container process io. It
open the stdin/stdout/stderr fifo from containerd, and pass them to
Dragonball, then don't bother with process io any more, eliminating
the need for an RPC for each io read/write operation.
In passfd io mode, the agent uses the vsock connections as the child
process's stdin/stdout/stderr, eliminating the need for a pipe
to bump data (in non-tty mode).

To enable this feature, build your rootfs using AGENT_POLICY=yes. The
default is AGENT_POLICY=no.
Building rootfs using AGENT_POLICY=yes has the following effects:
1. The kata-opa service gets included in the Guest image.
2. The agent gets built using AGENT_POLICY=yes.
After this patch, the shim calls SetPolicy if and only if a Policy
annotation is attached to the sandbox/pod. When creating a sandbox/pod
that doesn't have an attached Policy annotation:
1. If the agent was built using AGENT_POLICY=yes, the new sandbox uses
the default agent settings, that might include a default Policy too.
2. If the agent was built using AGENT_POLICY=no, the new sandbox is
executed the same way as before this patch.
Any SetPolicy calls from the shim to the agent fail if the agent was
built using AGENT_POLICY=no.
If the agent was built using AGENT_POLICY=yes:
1. The agent reads the contents of a default policy file during sandbox
start-up.
2. The agent then connects to the OPA service on localhost and sends
the default policy to OPA.
3. If the shim calls SetPolicy:
a. The agent checks if SetPolicy is allowed by the current
policy (the current policy is typically the default policy
mentioned above).
b. If SetPolicy is allowed, the agent deletes the current policy
from OPA and replaces it with the new policy it received from
the shim.
A typical new policy from the shim doesn't allow any future SetPolicy
calls.
4. For every agent rpc API call, the agent asks OPA if that call
should be allowed. OPA allows or not a call based on the current
policy, the name of the agent API, and the API call's inputs. The
agent rejects any calls that are rejected by OPA.
When building using AGENT_POLICY_DEBUG=yes, additional Policy logging
gets enabled in the agent. In particular, information about the inputs
for agent rpc API calls is logged in /tmp/policy.txt, on the Guest VM.
These inputs can be useful for investigating API calls that might have
been rejected by the Policy. Examples:
1. Load a failing policy file test1.rego on a different machine:
opa run --server --addr 127.0.0.1:8181 test1.rego
2. Collect the API inputs from Guest's /tmp/policy.txt and test on the
machine where the failing policy has been loaded:
curl -X POST http://localhost:8181/v1/data/agent_policy/CreateContainerRequest \
--data-binary @test1-inputs.json

Some vmms, such as dragonball, will actively help us
perform online cpu operations when doing cpu hotplug.
Under the old onlineCpuMem interface, it is difficult
to adapt to this situation.
So we modify the semantics of nb_cpus in onlineCpuMemRequest.
In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
semantics become that the number of online CPUs in the guest
needs to be guaranteed.

This change adds two fields to the Storage pb
FSGroup which is a group id that the runtime

FSGroupChangePolicy which is a policy to indicate
whether to always perform the group id ownership
change or only if the root directory group id
does not match with the desired group id.
These two fields will allow CSI plugins to indicate
to Kata that after the block device is mounted in
