For systems that have extreme robustness requirements (edge devices,
particularly those in difficult to access environments), it is important
that applications continue running in all circumstances. When the
application fails, Podman must restart it automatically to provide this
robustness. Otherwise, these devices may require customer IT to
physically gain access to restart, which can be prohibitively difficult.
Add a new `--on-failure` flag that supports four actions:
- **none**: Take no action.
- **kill**: Kill the container.
- **restart**: Restart the container. Do not combine the `restart`
action with the `--restart` flag. When running inside of
a systemd unit, consider using the `kill` or `stop`
action instead to make use of systemd's restart policy.
- **stop**: Stop the container.
To remain backwards compatible, **none** is the default action.

On FreeBSD, ENOTCONN can be reported if shutdown is called on a unix
domain socket where the remote end is already closed. This change
ignores those errors instead of printing an error message on container
exit.

This moves the code which sets the process capabilites for the exec to
oci_conmon_exec_linux.go since this is a linux-specific feature. Adding
a no-op stub for FreeBSD enables 'podman exec' when using the ocijail
runtime.

In case of a hard OS shutdown, containers may have a "removing"

It turns out that field names in syscall.Stat_t are platform-specific.
An alternative to this could change fixVolumePermissions to use
unix.Lstat since unix.Stat_t uses the same mmember name for Atim on both
Linux and FreeBSD.

This mount has never been standard on FreeBSD, preferring to use /tmp or
/var/tmp optionally with tmpfs to ensure data is lost on a reboot.

This contains a lot of code in common with container_internal_linux.go.
Subsequent commits will move the shared code to
container_internal_common.go to reduce the duplication.

podman update allows users to change the cgroup configuration of an existing container using the already defined resource limits flags
from podman create/run. The supported flags in crun are:
this command is also now supported in the libpod api via the /libpod/containers/<CID>/update endpoint where
the resource limits are passed inthe request body and follow the OCI resource spec format

The format used for setting the bind-mount-options annotations
in the kube yaml was incorrect and caused k8s to throw an error
when trying to play the generated kube yaml.
Fix the annotation format to match the rules of k8s.

If we get a SIGTERM immediately after Conmon starts but before we
record its PID in the database, we end up leaking a Conmon and
associated OCI runtime process. Inhibit shutdown using the logic
we originally wrote to prevent similar issues during container
creation to prevent this problem.
[NO NEW TESTS NEEDED] No real way to test this I can think of.

When a kube yaml has a volume set as empty dir, podman
will create an anonymous volume with the empty dir name and
attach it to the containers running in the pod. When the pod
is removed, the empy dir volume created is also removed.
Add tests and docs for this as well.

Commit 30e7cbccc1 accidentally added a deadlock as Podman was waiting
for the exit code to show up when the container transitioned to stopped.
Code paths that require the exit code to be written (by the cleanup
process) should already be using `(*Container).Wait()` in a deadlock
free way.
[NO NEW TESTS NEEDED] as I did not manage to a reproducer that would
work in CI. Ultimately, it's a race condition.
