* Introduces the `emptydir_mode` config flag to allow instructing the runtime
to create a block device for emptyDir volumes.
* The block device is created in the original emptyDir folder on the host
so that Kubelet can monitors its disk usage and evict the pod if it exceeds
its sizeLimit. This matches runc and virtio-fs.
* The block device's disk image file is sparse to minimize host disk
footprint.

The runtime-rs shim was failing to load its configuration when deployed
via kata-deploy because it couldn't correctly parse the ConfigPath passed
by containerd. The previous implementation naively skipped the first 2
bytes of the options and interpreted the rest as a UTF-8 string, which
doesn't work since containerd passes a properly serialized protobuf
message of type runtimeoptions.v1.Options.
This change adds the runtimeoptions.proto definition to the protocols
crate and updates the load_config function to correctly deserialize the
protobuf message and extract the config_path field, matching how the Go
runtime handles this via typeurl.UnmarshalAny.

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).

The +fieldpath option, specific to gogoprotobuf, enabled dynamic field
access in protobuf messages, allowing nested fields to be accessed via
string paths.
This change is part of a larger effort to transition to the official Go
protobuf library for better maintainability and community support.
Upon review, no instances of dynamic field access were found in the
codebase, confirming that the feature is not in use.
By removing this unused feature, we simplify the build process and make
it easier to complete the transition away from gogoprotobuf.

import_path is used as the default package when no input files specify

Currently, the script searches for .proto files within $GOPATH/.
Consequently, modifications to a definition file in the current working
directory won't influence the output .pb.go if the directory is outside
of $GOPATH. For developers, it's more intuitive to alter the local
codebase than the version stored in $GOPATH.
With this modification, the generated .pb.go files will be relative to
the current working directory, removing the need to clone this project
under $GOPATH/src/github.com/kata-containers.

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

Under the old onlineCpuMem interface, it is difficult

In the original semantics, nb_cpus represents the number of
newly added CPUs that need to be online. The modified
