This CL adds a test which verifies that the listening connections are restored
correctly after checkpoint. The test checkpoints when the tcp server is in the
listen state and verifies the read/write operations after the tcp server is
restored.

Adds support for per container stats in runsc based on cgroups.
1. Removed the 'cgroupfs' config flag.
2. Mounts the cgroups (/sys/fs/cgroup/<controller>) which will be shared
across all containers during root/pause container startup.
3. The container cgroups (eg:/sys/fs/cgroup/controller/<container-id>) are
mounted along with other container mounts before starting the container
process if the cgroups mount is in the spec.
Updates #172

Attempt to fix flaky port forward test using "netstat" in the container
to check the a process is listening on the port before attempting to
connect.
Also, re-enable the test in a seperate job, but w/ a soft fail. This
will be removed later in favor of adding port-forward to integration
tests to remove the high overhead of starting a new job (scheduling,
compiling runsc, downloading images, etc).

Port forward stream mode will be used for k8s. Stream mode takes a
UNIX socket and donates a connected FD to the sandbox in question,
and returns. No proxy process is kept around to do the transfer
and the UDS will be returned to containerd as the address on which
to send i/o to the forwarded port.
PiperOrigin-RevId: 521823250
Add portforward comand so that we can use runsc to forward connections
to container ports. This will eventually be supported in k8s.

Serves as a regression test for #8126.
Our unit tests didn't catch the issue because they run runsc with the flag
-TESTONLY-unsafe-nonroot. Docker tests are more e2e, they run tests in Docker
containers.
Fixes#8126

k8s.gcr.io/busybox:latest doesn't have the arm variant, so
let's use the upstream busybox and create /etc/recolv.conf symlink.

Linux behaves differently for regular files and dirs for poll(2)/select(2)
compared to epoll_ctl(2). The latter returns EPERM for file and dirs.
I've also changed host FDs to behave like the underlying FD in regards
to epoll to keep it compatible with docker.
Fixes#7134
