Add an exists subcommand to podman container and podman image that allows
users to verify the existence of a container or image by ID or name. The return
code can be 0 (success), 1 (failed to find), or 125 (failed to work with runtime).

Set the root propagation based on the properties of volumes and default
mounts. To remain compatibility, follow the semantics of Docker. If a
volume is shared, keep the root propagation shared which works for slave
and private volumes too. For slave volumes, it can either be shared or
rshared. Do not change the root propagation for private volumes and
stick with the default.
Fixes: #1834

The environment variable wasn't set, giving 0.0.0
It is a still a problem if you use python3 to build,
rather than make. You *need* to set $PODMAN_VERSION,
or your module and packages won't have the version.

CRIU uses iptables to lock and unlock the network during checkpoint and
restore. If Podman is running in Podman the automatic loading of modules
does not work and thus this commit pre-loads the necessary modules to
make sure the checkpoint test cases are not failing.

This adds the '--leave-running, -R' to the container-checkpoint man
page. As the information for '--all, -a' and '--latest, -l' was also
still missing it is included in this commit.

CRIU supports to leave processes running after checkpointing:
-R|--leave-running leave tasks in running state after checkpoint
runc also support to leave containers running after checkpointing:
--leave-running leave the process running after checkpointing
With this commit the support to leave a container running after
checkpointing is brought to Podman:
--leave-running, -R leave the container running after writing checkpoint to disk
Now it is possible to checkpoint a container at some point in time
without stopping the container. This can be used to rollback the
container to an early state:
$ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
3
$ podman container checkpoint -R -l
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
4
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
5
$ podman stop -l
$ podman container restore -l
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
4
So after checkpointing the container kept running and was stopped after
some time. Restoring this container will restore the state right at the
checkpoint.

For upcoming changes to the Checkpoint() functions this commit switches
checkpoint options from a boolean to a struct, so that additional
options can be passed easily to Checkpoint() without changing the
function parameters all the time.

otherwise runc will take by default the value used for creating the
container. Setting it explicit overrides its default value and we
won't end up trying to use a terminal when not available.

we need to allow users to expose ports to the host for the purposes
of networking, like a webserver. the port exposure must be done at
the time the pod is created.
strictly speaking, the port exposure occurs on the infra container.

scope out new kube subcommand where we can add generate. you can now generate kubernetes
YAML that will allow you to run the container in a kubernetes environment. When
The YAML description will always "wrap" a container in a simple v1.Pod description.
Tests and further documentation will be added in additional PRs.
This function should be considered very much "under heavy development" at
this point.

Also, don't use $PORT. These are too generic.
Make sure to read $LOGNAME _after_ the config.

pypodman does not currently support the version command. We want to
have as close to the same functionality between podman and pypodman,
so adding this command.
Also had to fix some validate errors.
