9321e1b21b oci: fix two incompatible issues with OCI spec
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.

a19cf28c26 agent/protocols: Remove some unnecessary include directives from protoc
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.

2b4520904c agent/protocols: Remove some unneeded dependencies for protocol generation
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.

1ca415d87e agent: exit from exec hangs if background process is present
This is the Rust porting of https://github.com/kata-containers/agent/pull/371

`read_stdout`/`read_stderr` is blocking rpc calls, if exec process
exited, these calls is on blocking state for reading on process's
term master fd, and can't get a chance to break the wait.

In this PR, `read_stdout`/`read_stderr` will not read directly from
a term master of a process, instead, it will first have to get
an fd to read from newly added `epoller.poll()`. `epoller.poll()` may returns:

- the term master fd of exec process, if the process is running.
- a fd(piped fd) will return EOF when reading to indicate that th process is exited.

0155fe1260 shimv2: handle ctx passed by containerd
Sometimes shim process cannot be shutdown because of container list
is not empty. This container list is written in shim service, while
creating container. We find that if containerd cancel its Create
Container Request due to timeout, but runtime didn't handle it properly
and continue creating action, then this container cannot be deleted at
all. So we should make sure the ctx passed to Create Service rpc call
is effective.

705182d04e agent: ignore updating cpuset error when update cgroups
The result of `cpuset_controller.set_cpus(&cpu.cpus)` is unwrapped,
this will lead creating container to fail if cpuset is set.

The sandbox's `CreateContainer` sequence is:

c, err := newContainer(s, &contConfig)
err = c.create()
  c.sandbox.agent.createContainer(c.sandbox, c) (1)
err = s.updateResources()
  oldCPUs, newCPUs, err := s.hypervisor.resizeVCPUs(sandboxVCPUs) (2)

cpuset only avaiable after `s.hypervisor.resizeVCPUs` has been called at (2),
and then cpuset is written to cgourps file.
