get_bool_value() in src/agent/src/config.rs includes a Result::or_else()
call with a trivial closure which can be replaced by a Result::or. This
removes a clippy warning.

RemoveContainerRequest results in calling to deleteContainer, according
to spec calling to RemoveContainer is idempotent and "must not return
an error if the container has already been removed", hence, don't
return error if the error reports that the container is not found.

The first incompatible issue is caused by a typo, "swapiness" should
be "swappiness". The second incompatible issue is caused by a serde
format. The struct LinuxBlockIODevice is introduced for convenience,
but it also changes serialized data, so "#[serde(flatten)]" should
be used for compatibility with OCI spec.

On pod delete, we were looking to read files that we had just deleted. In particular,
stopSandbox for QEMU was called (we cleanup up vmpath), and then QEMU's
save function was called, which immediately checks for the PID file.
Let's only update the persist store for QEMU if QEMU is actually
running. This'll avoid Error messages being displayed when we are
stopping and deleting a sandbox:
```
level=error msg="Could not read qemu pid file"
```
I reviewed CLH, and it looks like it is already taking appropriate
action, so no changes needed.
Ideally we won't spend much time saving state to persist.json unless
there's an actual error during stop/delete/shutdown path, as the persist will
also be removed after the pod is removed. We may want to optimize this,
as currently we are doing a persist store when deleting each container
(after the sandbox is stopped, VM is killed), and when we stop the sandbox.
This'll require more rework... tracked in:

oci.proto imports "google/protobuf/wrappers.proto", but doesn't appear to
use it, which causes a warning from protoc when we compile it. Remove the

The generate_go_sources() function in update-generate-proto.sh adds a
number of include directives to the protoc command line. Some of these
don't appear to be necessary to correctly compile the agent's protocol
files, so remove them.
Amongst other things were directives pointing at the old Kata1 runtime and
agent repositories. Those ones could be actively harmful by causing odd
dependencies of the Kata2 build on the Kata1 repositories.

src/agent/protocols/hack/update-generated-proto.sh checks for the presence
of protoc-gen-rust and ttrpc_rust_plugin, but it doesn't actually need
them. Those tools are needed to generate Rust code from the gRPC proto
files, but that's already handled in src/agent/protocols/build.rs using
Cargo for dependency management.
This script is only needed for the Go code, for which the other tools are
sufficient.

Currently QEMU is built inside the container, its tarball pulled to
the host, files removed then packaged again. Instead, let's run all
those steps inside the container and the resulting tarball will
be the final version. For that end, it is introduced the
qemu-build-post.sh script which will remove the uneeded files and
create the tarball.
The patterns for directories on qemu.blacklist had to be changed
to work properly with `find -path`.
