8080a5f8ec Revert "container,inspect: convert Entrypoint to array instead of a string"
It seems this breaks older version of `podman-remote` users hence it
looks like this patch would be a better candidate for podman `5.0`

Problem
* Client with `4.0` cannot interact with a server of `4.1`

Plan this patch for podman `5.0`

This reverts commit 0cebd158b6d8da1828b1255982e27fe9224310d0.

94df701512 Implement Podman Container Clone
podman container clone takes the id of an existing continer and creates a specgen from the given container's config
recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options

this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want
into clone over time allowing the user to clone with as much or as little of the original config as they want.

container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's

the current supported flags are:

--destroy (remove the original container)
--name (new ctr name)
--cpus (sets cpu period and quota)
--cpuset-cpus
--cpu-period
--cpu-rt-period
--cpu-rt-runtime
--cpu-shares
--cpuset-mems
--memory
--run

289270375a Pod Security Option support
Added support for pod security options. These are applied to infra and passed down to the
containers as added (unless overridden).

Modified the inheritance process from infra, creating a new function Inherit() which reads the config, and marshals the compatible options into an intermediate struct `InfraInherit`
This is then unmarshaled into a container config and all of this is added to the CtrCreateOptions. Removes the need (mostly) for special additons which complicate the Container_create
code and pod creation.

0dae50f1d3 Do not store the exit command in container config
There is a problem with creating and storing the exit command when the
container was created. It only contains the options the container was
created with but NOT the options the container is started with. One
example would be a CNI network config. If I start a container once, then
change the cni config dir with `--cni-config-dir` ans start it a second
time it will start successfully. However the exit command still contains
the wrong `--cni-config-dir` because it was not updated.

To fix this we do not want to store the exit command at all. Instead we
create it every time the conmon process for the container is startet.
This guarantees us that the container cleanup process is startet with
the correct settings.

1199733754 podman inspect add State.Health field for docker compat
podman inspect shows the healthcheck status in `.State.Healthcheck`,
docker uses `.State.Health`. To make sure docker scripts work we
should add the `Health` key. Because we do not want to display both keys
by default we only use the new `Health` key. This is a breaking change
for podman users but matches what docker does. To provide some form of
compatibility users can still use `--format {{.State.Healthcheck}}`. IT
is just not shown by default.

b53cb57680 Initial implementation of volume plugins
This implements support for mounting and unmounting volumes
backed by volume plugins. Support for actually retrieving
plugins requires a pull request to land in containers.conf and
then that to be vendored, and as such is not yet ready. Given
this, this code is only compile tested. However, the code for
everything past retrieving the plugin has been written - there is
support for creating, removing, mounting, and unmounting volumes,
which should allow full functionality once the c/common PR is
merged.

A major change is the signature of the MountPoint function for
volumes, which now, by necessity, returns an error. Named volumes
managed by a plugin do not have a mountpoint we control; instead,
it is managed entirely by the plugin. As such, we need to cache
the path in the DB, and calls to retrieve it now need to access
the DB (and may fail as such).

Notably absent is support for SELinux relabelling and chowning
these volumes. Given that we don't manage the mountpoint for
these volumes, I am extremely reluctant to try and modify it - we
could easily break the plugin trying to chown or relabel it.

Also, we had no less than *5* separate implementations of
inspecting a volume floating around in pkg/infra/abi and
pkg/api/handlers/libpod. And none of them used volume.Inspect(),
the only correct way of inspecting volumes. Remove them all and
consolidate to using the correct way. Compat API is likely still
doing things the wrong way, but that is an issue for another day.

4d800a5f45 Store cgroup manager on a per-container basis
When we create a container, we assign a cgroup parent based on
the current cgroup manager in use. This parent is only usable
with the cgroup manager the container is created with, so if the
default cgroup manager is later changed or overridden, the
container will not be able to start.

To solve this, store the cgroup manager that created the
container in container configuration, so we can guarantee a
container with a systemd cgroup parent will always be started
with systemd cgroups.

Unfortunately, this is very difficult to test in CI, due to the
fact that we hard-code cgroup manager on all invocations of
Podman in CI.
