The reserved annotation io.podman.annotations.volumes-from is made public to let user define volumes-from to have one container mount volumes of other containers.
The annotation format is: io.podman.annotations.volumes-from/tgtCtr: "srcCtr1:mntOpts1;srcCtr2:mntOpts;..."

This mirrors how the Docker API handles things, allowing us to be
more compatible with Docker and more verbose on the Libpod API.
Stats are given as per network interface in the container, but
still aggregated for `podman stats` and `podman pod stats`
display (so the CLI does not change, only the Libpod and Compat
APIs).

When inspecting a container that does not define any health check, the health field should return nil. This matches docker behavior.
Signed-off-by: Ashley Cui <acui@redhat.com>
When InitialDelaySeconds in the kube yaml is set for a helthcheck,
don't update the healthcheck status till those initial delay seconds are over.
We were waiting to update for a failing healtcheck, but when the healthcheck
was successful during the initial delay time, the status was being updated as healthy
immediately.
This is misleading to the users wondering why their healthcheck takes
much longer to fail for a failing case while it is quick to succeed for
a healthy case. It also doesn't match what the k8s InitialDelaySeconds
does. This change is only for kube play, podman healthcheck run is
unaffected.

Add --rdt-class=COS to the create and run command to enable the
assignment of a container to a Class of Service (COS). The COS
represents a part of the cache based on the Cache Allocation Technology
(CAT) feature that is part of Intel's Resource Director Technology
(Intel RDT) feature set. By assigning a container to a COS, all PID's of
the container have only access to the cache space defined for this COS.
The COS has to be pre-configured based on the resctrl kernel driver.
cat_l2 and cat_l3 flags in /proc/cpuinfo represent CAT support for cache
level 2 and 3 respectively.

be stuck in the `wait $ctr` command since it will continue restarting.

The `Exists` field of the `RemoteSocket` struct is marshaled to json with the
`omitempty` setting. This has the disadvantage that by default `podman info`
shows a `remotePath` entry (the remote path is set in
`pkg/domain/infra/abi/systems.go`: `(*ContainerEngine).Info`) but not that this
path does not exist:
```
❯ podman info --format json | jq .host.remoteSocket
{
"path": "/run/user/1000/podman/podman.sock"
}
```
By removing the `omitempty`, we ensure that the existence is always shown:
```
❯ bin/podman info --format json | jq .host.remoteSocket
{
"path": "/run/user/1000/podman/podman.sock",
"exists": false
}

We never ever close the stream so we do not need the Close() function in
th ebackend, the caller should close when required which may no be the
case, i.e. when os.Stdout/err is used.
This should not be a breaking change as the io.Writer is a subset of
io.WriteCloser, therfore all code should still compile while allowing to
pass in Writers without Close().
This is useful for podman top where we exec ps in the container via
podman exec.

Implement means for reflecting failed containers (i.e., those having
exited non-zero) to better integrate `kube play` with systemd. The
idea is to have the main PID of `kube play` exit non-zero in a
configurable way such that systemd's restart policies can kick in.
When using the default sdnotify-notify policy, the service container
acts as the main PID to further reduce the resource footprint. In that
case, before stopping the service container, Podman will lookup the exit
codes of all non-infra containers. The service will then behave
according to the following three exit-code policies:
- `none`: exit 0 and ignore containers (default)
- `any`: exit non-zero if _any_ container did
- `all`: exit non-zero if _all_ containers did
The upper values can be passed via a hidden `kube play
--service-exit-code-propagation` flag which can be used by tests and
later on by Quadlet.
In case Podman acts as the main PID (i.e., when at least one container
runs with an sdnotify-policy other than "ignore"), Podman will continue
to wait for the service container to exit and reflect its exit code.
Note that this commit also fixes a long-standing annoyance of the
service container exiting non-zero. The underlying issue was that the
service container had been stopped with SIGKILL instead of SIGTERM and
hence exited non-zero. Fixing that was a prerequisite for the exit-code
propagation to work but also improves the integration of `kube play`
with systemd and hence Quadlet with systemd.

Add --restart flag to pod create to allow users to set the
restart policy for the pod, which applies to all the containers
in the pod. This reuses the restart policy already there for
containers and has the same restart policy options.
Add "never" to the restart policy options to match k8s syntax.
It is a synonym for "no" and does the exact same thing where the
containers are not restarted once exited.
Only the containers that have exited will be restarted based on the
restart policy, running containers will not be restarted when an exited
container is restarted in the same pod (same as is done in k8s).

go swagger has a flat namespace so it doesn't handle name conflicts at
all. The libpod info response uses the Info struct from some docker dep
instead. Because we cannot change the docker dependency simply rename
the Info struct, but only via swagger comment not the go actual struct.

Currently Podman prevents SELinux container separation,
when running within a container. This PR adds a new
--security-opt label=nested
When setting this option, Podman unmasks and mountsi
/sys/fs/selinux into the containers making /sys/fs/selinux
fully exposed. Secondly Podman sets the attribute
run.oci.mount_context_type=rootcontext
This attribute tells crun to mount volumes with rootcontext=MOUNTLABEL
as opposed to context=MOUNTLABEL.
With these two settings Podman inside the container is allowed to set
its own SELinux labels on tmpfs file systems mounted into its parents
container, while still being confined by SELinux. Thus you can have
nested SELinux labeling inside of a container.
